Detailed Description
The following are preferred embodiments of the present application, and it should be noted that modifications and variations can be made by those skilled in the art without departing from the principle of the present application, and these modifications and variations are also considered as the protection scope of the present application.
Before the technical scheme of the application is described, the technical problems in the related art are described in detail.
With the continuous development of electronic devices, the requirements of people on the transmitting power of the electronic devices are continuously increased. Among them, a power amplifier in an electronic device is generally used to power amplify a signal to meet a requirement of a transmission power. However, the current of the power amplifier is easily affected by temperature, thereby reducing the operation performance of the power amplifier.
Specifically, for example, a mobile radio frequency front-end circuit generally includes a receiving circuit and a transmitting circuit. The transmitting circuit part mainly comprises circuits such as a Power Amplifier (PA), a filter, a switch, a coupler and the like. Among them, the power amplifier is the most critical circuit part in the transmitting circuit. The main current android mobile phone mainly uses a high-pass platform and a platform (Media tek.inc, MTK) of concurrent technology stock limited company. The main parameters set by the two platforms aiming at the power amplifier on the transmitting channel of the mobile phone comprise indexes such as working voltage, static working current, input power and the like. The setting of the quiescent operating current parameter mainly affects the linearity of the power amplifier. Also, the quiescent operating current also affects the performance of the power amplifier, and its affected metrics include power consumption, adjacent channel leakage ratio (Adjacent Channel Leakage Ratio, ACLR), conducted spurious emissions (Conducted Spurious Emission, CSE), and spectral emission templates (Spectrum Emission Mask, SEM), among others. Typically these metrics are all tested at maximum power transmitted.
At present, two static working currents, namely a static working current under high power and a static working current under low power, are generally introduced in the same standard and the same frequency band, and different static working currents are called by detecting the transmitting power so as to ensure the normal operation of the power amplifier.
For example, indexes under normal conditions (15 ℃ C. To 35 ℃ C.) and limit conditions (high temperature: 55 ℃ C., low temperature: 10 ℃ C.) for adjacent channel leakage ratio are respectively specified in 3GPP TS 36.521-1 of the third Generation partnership project (3rd Generation Partnership Project,3GPP), and the conducted spurious emission and spectrum emission templates only need to test indexes under normal temperature. Because the static working current can influence the indexes, the static working current value meeting the adjacent channel leakage ratio at normal temperature, the conduction spurious emission and spectrum emission template and the adjacent channel leakage ratio under the limit condition is needed to be adopted.
However, in the limit case, carrier mobility in the power amplifier is greatly different from that in the normal temperature case, so that the performance of the power amplifier is greatly different from that in the normal temperature case. It can also be understood that, since the temperature has a larger influence on the current of the power amplifier, the power consumption, the conduction spurious emission, the spectrum emission template and other indexes related to the current are greatly influenced, so that the working performance of the power amplifier is reduced.
In view of this, in order to solve the above-described problems, the present application provides a current regulation method. Referring to fig. 1, fig. 1 is a flow chart illustrating a current adjusting method according to an embodiment of the application.
The present embodiment provides a current adjustment method applied to the power amplifier 20, and the current adjustment method includes S100, S200, S300, S400, S500. Among them, S100, S200, S300, S400, S500 are described in detail below.
And S100, acquiring a temperature value and a current value of the power amplifier 20.
The temperature value of the power amplifier 20 is affected by various factors, and the current value of the power amplifier 20 is affected by the temperature value. In one embodiment, the temperature value of the power amplifier 20 is approximately equal to the temperature value of the environment. In another embodiment, the temperature value of the power amplifier 20 is affected by other mating components. For example, when the heat dissipation member operates with low efficiency, the temperature of the power amplifier 20 is liable to rise. Or when the heat dissipation member operates with high efficiency, the temperature of the power amplifier 20 is easily lowered.
In yet another embodiment, the temperature value of the power amplifier 20 changes as the operating environment changes. For example, the power amplifier 20 is transferred from the normal temperature environment to the extreme temperature environment. The environment temperature range of the normal temperature environment can be 15-35 ℃, the extreme temperature environment comprises a high temperature environment and a low temperature environment, the environment temperature of the high temperature environment can be 35-55 ℃, and the environment temperature of the low temperature environment can be 15-10 ℃.
In this embodiment, by obtaining the temperature value and the current value of the power amplifier 20, the temperature value and the current value of the current power amplifier 20 during operation are obtained, which provides a basis for effective and accurate current adjustment.
Optionally, the power amplifier 20 comprises at least one transistor.
Optionally, the current of the power amplifier 20 includes, but is not limited to, a static operating current, a dynamic operating current, and the like.
S200, judging whether the temperature value is in a preset temperature range.
The preset temperature range in this embodiment can be adjusted according to the requirement. In one embodiment, the specification requirements within a temperature range of 15 ℃ to 35 ℃ may be met according to the requirements of the third generation partnership project. Alternatively, the preset temperature range is 15 ℃ to 35 ℃.
In another embodiment, the preset temperature range may be adjusted according to a seasonal scene used by the user. Optionally, the preset temperature range is at least one of-10 ℃ to 0 ℃, 0 ℃ to 10 ℃, 10 ℃ to 20 ℃, 20 ℃ to 30 ℃ and 30 ℃ to 40 ℃.
In yet another embodiment, the preset temperature range may be adjusted according to the product requirements of the power amplifier 20. For example, the operating environment of the power amplifier 20 is at a normal temperature environment or an extreme temperature environment. When the power amplifier 20 is operated in a normal temperature environment, the preset temperature range is optionally at least one of 5-15 deg.c, 15-25 deg.c, 25-35 deg.c. When the power amplifier 20 is operated in an extreme temperature environment, the preset temperature range is optionally at least one of-55 ℃ to-45 ℃, -45 ℃ to-35 ℃, -35 ℃ to-25 ℃, -25 ℃ to-15 ℃, -15 ℃ to-5 ℃, -5 ℃ to-5 ℃, 35 ℃ to 45 ℃, 45 ℃ to 55 ℃, 55 ℃ to 65 ℃, 65 ℃ to 75 ℃, 75 ℃ to 85 ℃, 85 ℃ to 95 ℃.
In this embodiment, whether the temperature value is within the temperature range in which the current value needs to be adjusted can be determined by comparing whether the temperature value is within the preset temperature range.
S300, when the temperature value is in the preset temperature range, acquiring a first preset current value corresponding to the preset temperature range.
Then, when the temperature value is within the preset temperature range, a first preset current value corresponding to the preset temperature range is obtained. This means that if the current temperature value of the power amplifier 20 is within the preset temperature range, a preset current value corresponding to the preset temperature range can be obtained, which provides a basis for the subsequent current adjustment.
The preset current value is a pre-stored current value according to the requirements of users or products. In one embodiment, the preset current value is set according to the user's needs. For example, a user needs a low power loss power amplifier 20. The current values of the power amplifier 20 with low power loss are set to preset current values by counting the current values of one or more electronic devices in different temperature ranges.
In another embodiment, the preset current value is set according to the product demand. For example, by counting the electronic device emission index performance (e.g., power consumption, conducted spurious emissions, spectrum emission templates, etc.) for one or more electronic devices at different current values over different temperature ranges. And then selecting current values which can enable the emission index to reach better performance in each temperature range, and setting the current values as preset current values.
And the preset current value can also be a current value input by a user or a current value obtained in real time through channels such as a network, bluetooth and the like.
S400, judging whether the current value of the power amplifier 20 is equal to the first preset current value.
Whether the current value of the power amplifier 20 is equal to the first preset current value is compared to determine whether the current value of the power amplifier 20 needs to be adjusted.
When the current value of the power amplifier 20 is not equal to the first preset current value, it indicates that the current value of the power amplifier 20 cannot meet the preset requirement, and the current value of the power amplifier 20 needs to be adjusted. The preset requirement herein may mean that the emission index of the power amplifier 20 does not meet the user or product requirement. For example, the power consumption of the power amplifier 20 does not satisfy the user demand range. Or, at least one index of the power consumption, the conduction spurious emission, the spectrum emission template, and the spectrum emission template does not satisfy the product requirement range, and the operation performance of the power amplifier 20 is reduced, so that the current value of the power amplifier 20 needs to be adjusted to improve the operation performance of the power amplifier 20.
In addition, when the current value of the power amplifier 20 is equal to the first preset current value, it indicates that the current value of the power amplifier 20 meets the preset requirement, and the current value of the power amplifier 20 is not required to be adjusted.
S500, when the current value of the power amplifier 20 is not equal to the first preset current value, adjusting the current value of the power amplifier 20 to be equal to the first preset current value, wherein the performance of the power amplifier 20 in the preset temperature range and when the current is equal to the first preset current value is better than the performance of the power amplifier 20 in the preset temperature range and when the current is equal to the current value.
When it is confirmed that the current value of the power amplifier 20 needs to be adjusted, the current value of the power amplifier 20 can be equal to the first preset current value according to the first preset current value, so that the current value of the power amplifier 20 is matched with the preset current value in the current preset temperature range, the requirement of a user or a product on the current value is met, the influence of temperature on the current value of the power amplifier 20 is reduced, and the working performance of the power amplifier 20 is improved.
The performance of the power amplifier 20 is an index performance related to current in the power amplifier 20. Optionally, the metrics include, but are not limited to, at least one of power consumption, conducted spurious emissions, spectrum emission templates, and spectrum emission templates.
Alternatively, in one embodiment, the current value of the power amplifier 20 is made equal to the first preset current value by direct adjustment. The method can quickly adjust the current value of the power amplifier 20, and is suitable for when the working environment of the power amplifier 20 suddenly changes, for example, the working environment of the power amplifier 20 suddenly changes from a normal temperature environment to an extreme temperature environment.
In another embodiment, the current is adjusted by supplementing the value: a first difference between the current value of the power amplifier 20 and a first preset current value is calculated. It is determined whether the current value of the power amplifier 20 is greater than a first preset current value.
When the current value of the power amplifier 20 is greater than the first preset current value, the current value of the power amplifier 20 is reduced by a first difference value so that the current value of the power amplifier 20 is equal to the first preset current value. When the current value of the power amplifier 20 is smaller than the first preset current value, the current value of the power amplifier 20 is increased by a first difference value, so that the current value of the power amplifier 20 is equal to the first preset current value.
In this method, the current value of the power amplifier 20 has a variable process, so that the possibility of malfunction of the power amplifier 20 caused by abrupt adjustment can be reduced, and the operation stability of the power amplifier 20 can be improved.
In summary, the current adjusting method provided in the present embodiment can match the current value in the preset temperature range corresponding to the current value according to the current temperature value of the power amplifier 20, so as to improve the working performance of the power amplifier 20.
Referring to fig. 2, fig. 2 is a flow chart of a current adjusting method according to another embodiment of the application. The current regulation method further includes S210, S220, S230, S240, S250. The details of S210, S220, S230, S240, and S250 are as follows.
After S200 "determine whether the temperature value is within the preset temperature range", the method further includes:
s210, when the temperature value is not in the preset temperature range, obtaining the maximum value of the preset temperature range: a first temperature value, and a minimum value of the preset temperature range: a second temperature value.

The present embodiment is described for a current regulation method when the temperature value is not within a preset temperature range. The first temperature value and the second temperature value are endpoints of a preset temperature range, and the first temperature value is larger than the second temperature value. Since the temperature value is not within the preset temperature range, the range of the current temperature value of the power amplifier 20 can be further determined by the first temperature value and the second temperature value.
And when the temperature value is larger than the first temperature value, acquiring a second preset current value corresponding to the temperature range value. It is further determined whether the current value of the power amplifier 20 is equal to a second preset current value to determine whether the current value of the power amplifier 20 needs to be adjusted. When the current value of the power amplifier 20 is not equal to the second preset current value, the current value of the power amplifier 20 is made to be equal to the second preset current value, so that the current regulation of the power amplifier 20 is realized, and the working performance of the power amplifier 20 is improved.
Referring to fig. 3 and fig. 4, fig. 3 is a flow chart of a current adjusting method according to another embodiment of the application.

Among them, S221, S222, S223 are described in detail below.
After determining whether the temperature value is greater than the first temperature value in S220", the method further includes:
s221, when the temperature value is smaller than the second temperature value, acquiring a third preset current value.
S222, judging whether the current value of the power amplifier 20 is equal to the third preset current value.
S223, when the current value of the power amplifier 20 is not equal to the third preset current value, adjusting the current value of the power amplifier 20 to be equal to the third preset current value, wherein the performance when the power amplifier 20 is smaller than the second temperature value and the current is equal to the third preset current value is better than the performance when the power amplifier 20 is smaller than the second temperature value and the current is equal to the current value.
The present embodiment is further described with respect to a current regulation method when the temperature value is not within a preset temperature range.
When the temperature value is smaller than the first temperature value and the temperature value is not within the preset range, i.e. between the second temperature value and the first temperature value, it indicates that the current temperature value of the power amplifier 20 is smaller than the second temperature value.
And when the temperature value is smaller than the second temperature value, acquiring a third preset current value corresponding to the temperature range value. It is further determined whether the current value of the power amplifier 20 is equal to a third preset current value to determine whether the current value of the power amplifier 20 needs to be adjusted. When the current value of the power amplifier 20 is not equal to the third preset current value, the current value of the power amplifier 20 is made to be equal to the third preset current value, so that the current regulation of the power amplifier 20 is realized, and the working performance of the power amplifier 20 is improved.
For example, when the preset temperature range is 15 ℃ to 35 ℃, the temperature value and the current value of the power amplifier 20 are obtained; judging whether the temperature value is in a preset temperature range or not; when the temperature value of the power amplifier 20 is greater than or equal to 15 ℃ and less than or equal to 35 ℃, namely within a set temperature range, a first preset current value is obtained; comparing the current value with a first preset current value; the current value of the power amplifier 20 is made equal to a first preset current value.
When the temperature value of the power amplifier 20 is not 15-35 ℃, acquiring a first temperature value of 35 ℃ and a second temperature value of 15 ℃; judging whether the temperature value is larger than a first temperature value or not; when the temperature value of the power amplifier 20 is greater than 35 ℃, namely greater than the first temperature value, a second preset current value is obtained; comparing the current value with a second preset current value; the current value of the power amplifier 20 is made equal to the second preset current value.
When the temperature value is smaller than the first temperature value, judging whether the temperature value is smaller than the second temperature value; when the temperature value of the power amplifier 20 is less than 15 ℃, namely less than the second temperature value, a third preset current value is obtained; comparing the current value with a third preset current value; the current value of the power amplifier 20 is made equal to the third preset current value.
In summary, by combining the preset range, the first temperature value, and the comparison result between the second temperature value and the current temperature value of the power amplifier 20, the temperature range corresponding to the current temperature value of the power amplifier 20 is determined, so as to implement current regulation and improve the working performance of the power amplifier 20.
In one embodiment, when the preset current value is a current value which enables the emission index to reach better performance in different temperature ranges, by comparing the temperature value of the power amplifier 20 with the preset normal temperature range, the high temperature range and the low temperature range, whether the temperature value is matched with the temperature value of the power amplifier 20 or not is further confirmed, so as to optimize the emission index in the normal temperature environment and the extreme temperature environment, that is, greatly improve the emission index performance of the electronic device in different temperatures, so as to improve the working performance of the power amplifier 20, enable the electronic device to be in a good working state in different temperatures, and reduce the conditions of insufficient margin or exceeding standard of the electronic device in the authentication process. Among other transmission metrics, but not limited to, power consumption, adjacent channel leakage ratio, conducted spurious emissions, and spectrum emission templates, etc.
Alternatively, when the current value is unstable, the current value of the power amplifier 20 may be adjusted by combining a preset current value with a complementary value.
For example, after the multi-step determination, the current value of the power amplifier 20 needs to be adjusted to a second preset current value. However, since the current value of the power amplifier 20 is unstable at this time and a process of changing the current value of the power amplifier 20 to the second preset current value is required, the stability of the mutual cooperation of the components in the power amplifier 20 is ensured.
In one current regulation method, first, a first preset current value is obtained. Then, a second difference between the first preset current value and the second preset current value is calculated. The second difference is increased or decreased to make the current value of the present power amplifier 20 equal to the second preset current value.
In another current regulation method, first, a third preset current value is obtained. Then, a third difference between the first preset current value and a third stored current value is calculated. The third difference is increased or decreased to make the current value of the present power amplifier 20 equal to the second preset current value.
In the method, unstable current values can be avoided from being acquired, and the difference value between the determined preset current values is used as a compensation value to realize current regulation, so that the working stability of the power amplifier 20 can be improved, and the accuracy of current regulation can be improved.
The current adjustment method in the present embodiment is suitable for the operating environment where the temperature value of the power amplifier 20 changes more frequently. First case: the operating environment of the power amplifier 20 often changes. For example, the operating environment of the power amplifier 20 is switched between a cold temperate zone region, a medium temperate zone region, a warm temperate zone region, a subtropical zone region, and a tropical zone region. For example, the first day power amplifier 20 operates in a tropical region and the second day power amplifier 20 operates in a cold temperate region. Second case: the operating environment of the power amplifier 20 is unchanged, but the ambient temperature varies widely. For example, the power amplifier 20 operates in an area where the temperature daily changes greatly. For example, bronning in the united states has a day air temperature of 7 ℃ and a night air temperature of 49 ℃ below zero, with a day-to-night temperature differential of 56 ℃.
Referring to fig. 5 and fig. 6 together, fig. 5 is a schematic structural diagram of a power amplifier according to an embodiment of the application. Fig. 6 is a schematic flow chart of a current regulation method according to another embodiment of the application. The current regulation method further includes S110. The details of S110 are as follows.
The periphery of the power amplifier 20 is provided with at least one thermosensitive element 21, S100 "for obtaining the temperature value and the current value of the power amplifier 20", which includes:
S110, acquiring the temperature value of the at least one thermosensitive element 21 as the temperature value of the power amplifier 20.
The power amplifier 20 in the present embodiment includes a thermosensitive member 21, and the thermosensitive member 21 is a member sensitive to temperature, which is susceptible to various factors around its periphery, and the temperature value or specific parameter of which is susceptible to change.

The number, shape, and size of the thermosensitive member 21 are not limited in this embodiment, and the thermosensitive member 21 may be provided at the periphery of the power amplifier 20.

Referring to fig. 5 and fig. 7 again, fig. 7 is a flow chart of a current adjusting method according to another embodiment of the application. The current regulation method further includes S112, S113, S114, S115, S116. The details of S112, S113, S114, S115, and S116 are as follows.

Then, the temperature value of the higher thermosensitive member 21 is used as the temperature value of the power amplifier 20 for the subsequent comparison. When the temperature value changes to an increasing trend, a higher temperature value of the heat-sensitive member 21 means more sensitive to the change in temperature. Therefore, the temperature value of the heat sensitive element 21 with higher temperature value is selected as the subsequent comparison of the temperature value of the power amplifier 20, so that the error of judgment caused by unstable temperature value of the power amplifier 20 can be reduced, and the accuracy of the current regulating method can be improved.
Optionally, determining whether the third temperature value is greater than the fourth temperature value;
When the third temperature value is larger than the fourth temperature value, acquiring the fourth temperature value;
and when the third temperature value is smaller than or equal to the fourth temperature value, acquiring the third temperature value.
When the temperature value changes to a decreasing trend, a lower temperature value of the thermosensitive member 21 means more sensitive to the change in temperature. Therefore, the temperature value of the thermosensitive element 21 with lower temperature is selected as the subsequent comparison of the temperature value of the power amplifier 20, so that the error of judgment caused by unstable temperature value of the power amplifier 20 can be reduced, and the accuracy of the current regulating method can be improved.
In summary, the temperature values of the at least two thermosensitive members 21 can be selected according to the trend of the temperature variation of the actual power amplifier 20, so as to improve the accuracy of the current adjusting method.

The comparison of the temperature value of the power amplifier 20 can reduce the judgment error caused by unstable temperature value of the power amplifier 20, and improve the accuracy of the current regulation method.

The first vertical distance (as shown by H1 in fig. 9) can also be understood as the distance between the first thermosensitive member 211 and the power amplifier 20. It is also understood that the first vertical distance is a vertical distance between a surface of the first heat sensitive member 211 on a side close to the power amplifier 20 and a surface of the power amplifier 20 on a side close to the first heat sensitive member 211.
