The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the present application.
In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is to be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with one another without conflict.
It should be noted that the term "first\second\third" in relation to the embodiments of the present application is merely to distinguish similar objects and does not represent a specific ordering for the objects, it being understood that the "first\second\third" may be interchanged in a specific order or sequence, where allowed, to enable the embodiments of the present application described herein to be practiced in an order other than that illustrated or described herein.
Before describing embodiments of the present application in further detail, the terms and terminology involved in the embodiments of the present application will be described, where the terms and terminology involved in the embodiments of the present application are suitable for the following explanation:
fifth generation mobile communication technology: 5th Generation Mobile Communication Technology,5G;
a power amplifier: power Amplifier, PA;
a power management unit: power Management Unit PMU, which may be simply called a power supply, is used to supply power to different devices such as a main chip (e.g., a power management chip, a PA chip);
and a power management chip: power Management IC, PMIC, generally provides Power to specific functional modules in the terminal device.
Fig. 1 is a schematic diagram showing the constitution of an amplifier in the prior art. As shown in fig. 1, the amplifier comprises a driver stage 101, a power stage 102 and a bias circuit 103. The driver stage 101 acquires a radio frequency input signal rf_in, performs a pre-stage amplification, and transmits the signal to the power stage 102 (also referred to as an amplifying stage), and the power stage 102 performs a final-stage amplification to obtain a radio frequency output signal rf_out. The input terminal of the bias circuit 103 (bias circuit) is connected to the voltage VBATT, and two output terminals of the bias circuit 103 are respectively connected to the driving stage 101 and the power stage 102, so as to provide the bias current Ibias1 for the driving stage 101 and provide the bias current Ibias2 for the power stage 102.
The related power supply modes in the prior art are described below in connection with an external power supply scheme. Fig. 2 shows a schematic diagram of a connection of a power amplifier system. In this power amplifier system, PMU and PMIC constitute a PA supply structure, as shown in fig. 2. Wherein the PMU provides a voltage VBATT to power the PMIC, which provides the required voltages (VCC 1, VCC 2) for the amplifier PA. Wherein, VCC1 end and VCC2 end of the amplifier PA are led out and connected with PMIC directly; the ports VCC1 and VCC2 for powering the amplifier PA are typically connected to the same port VPA of the PMIC, i.e. both the driver stage and the power stage of the amplifier PA are powered by the same voltage. However, since VCC1 and VCC2 are connected together with a larger current on the path, for application scenarios with higher current, such as low voltage and high power, the current may exceed the maximum current limit of the PMIC port, thereby causing the amplifier to operate abnormally.
Based on this, the embodiment of the application provides a flexibly configurable amplifier power supply architecture, so that the amplifier can be flexibly applied to different power supply modes, the configuration scheme of the PMIC of the system is more free and convenient, the cost and the area optimization of the scheme of the system are achieved, and the risk of burning the PMIC caused by overlarge current is avoided.
Embodiments of the present application are described in detail below with reference to the accompanying drawings.
In an embodiment of the present application, referring to fig. 3, a schematic diagram of a composition structure of a power amplifier system provided in an embodiment of the present application is shown. As shown in fig. 3, the power amplifier system 50 includes: amplifier 40 and a power supply. The power supply comprises a first power supply module 501 and a second power supply module 502 connected with the amplifier 40, the amplifier 40 comprises a driving stage module 401 and an amplifying stage module 402, an output end of the driving stage module 401 is connected with an input end of the amplifying stage module 402, and a power supply mode of the power amplifier system 50 comprises a first power supply mode and a second power supply mode, wherein:
in the first power supply mode, the driving stage module 401 and the amplifying stage module 402 are connected with the first power supply module 501 or the second power supply module 502, so as to supply power to the driving stage module 401 and the amplifying stage module 402 through the first power supply module 501 or the second power supply module 502;
in the second power supply mode, the driving stage module 401 is connected with the first power supply module 501 to supply power to the driving stage module 401 through the first power supply module 501; the amplification stage module 402 is connected to a second power supply module 502 to supply power to the amplification stage module 402 via the second power supply module 502.
In this embodiment, the first power supply module 501 and the second power supply module 502 are different modules in the same power management chip PMIC. In other embodiments, the first power supply module 501 and the second power supply module 502 may be modules of different power management chips.
Here, the first power supply mode may be used to supply power to the amplifier 40 when the current of the amplifier 40 does not exceed the current limit of the power supply module, and the second power supply mode may be used to supply power to the amplifier 40 when the current of the amplifier 40 exceeds or approaches the current limit of the power supply module.
In this way, in the embodiment of the present application, by switching the connection modes between the driving stage module 401 and the amplifying stage module 402 and each power supply module, in the second power supply mode, the two power supply modules supply power respectively, so as to realize current splitting, and better protect the power supply, and avoid the problems that the power supply module limits the current due to overlarge current, thereby causing the abnormal operation of the amplifier 40, or the power supply module is burnt out, etc. In addition, since the power supply module can be flexibly connected with the amplifier 40, the amplifier 40 can also be compatible with various power supply modes, such as average power tracking power supply, envelope tracking power supply and the like, so as to flexibly match various application scenes.
In some embodiments, the voltages or currents output by the first power module 501 and the second power module 502 are different. For example, the voltage output by the first power supply module 501 is less than the voltage output by the second power supply module 502. In other embodiments, both may be the same.
In some embodiments, the first power module 501 and the second power module 502 are each configured to output a variable voltage or current according to a power mode. For example, the first power supply module 501 and the second power supply module 502 provide variable voltages according to the working requirements of the driving stage module 401 and the amplifying stage module 402, respectively, where the voltages output by the first power supply module 501 and the second power supply module 502 are different. In other embodiments, the first power supply module 501 and the second power supply module 502 may output a fixed voltage or a fixed current according to a power supply mode.
In some embodiments of the present application, a device, a circuit, etc. with a power switching function may be disposed between the amplifier 40 and the power supply, so as to implement switching the driving stage module 401 and/or the amplifying stage module 402 to be connected to the first power supply module 501 or the second power supply module 502.
Next, a specific implementation of the embodiment of the present application will be described in detail taking an example of implementing connection of the driving stage module 401 and the amplifying stage module 402 to different power supply modules through the switching unit 403.
Wherein the switching unit 403 is configured to connect the amplifying stage module 402 and/or the driving stage module 401 to a corresponding power supply module according to a power supply mode. In particular, the switching unit 403 may be integrated within the amplifier 40 as part of the amplifier 40; or may be integrated with the first power module 501 and the second power module 502 as part of the power supply of the power amplifier system; alternatively, the switching unit 403 may be provided as a separate part of the power amplifier system 50 or within another chip, independently of the amplifier 40, the first power supply module 501 and the second power supply module 502. The embodiment of the present application is not particularly limited thereto.
As shown in fig. 3, the switching unit 403 may include a first switch S1 and a second switch S2, wherein the first switch S1 and the second switch S2 may be single pole multi-throw switches, a fixed end of the first switch S1 is connected to the driving stage module 401, and a fixed end of the second switch S2 is connected to the amplifying stage module 402. In the present embodiment, the active end of the first switch S1 is referred to as a port (1), the active end of the second switch S2 is referred to as a port (2), the output end of the second power supply module 502 is referred to as a port (3) (or the port (3) represents an interface connected to the output end of the second power supply module 502), and the output end of the first power supply module 501 is referred to as a port (4) (or the port (4) represents an interface connected to the output end of the first power supply module 501).
It will be appreciated that in the implementation shown in fig. 3, the first switch S1 and the second switch S2 are both single pole double throw switches.
On the basis of fig. 3, fig. 4 shows several different connection schemes of the switching unit 403. Where VCC1 represents a port for connecting a first voltage provided by the first power supply module 501 and VCC2 represents a port for connecting a second voltage provided by the second power supply module 502.
In the case that the power supply mode is the first power supply mode, the port (1) and the port (2) are connected together and connected to the same power supply module, so that the same power supply module supplies power to the driving stage module 401 and the amplifying stage module 402 simultaneously. For example, as shown in fig. 4, the port (1) and the port (2) are both connected to the port (4), and the first voltage VCC1 provided by the first power supply module 501 serves as the power supply voltage for the driving stage module 401 and the amplifying stage module 402; alternatively, the port (1) and the port (2) are both connected to the port (3), and the second voltage VCC2 supplied by the first power supply module 501 serves as the power supply voltage of the driver stage module 401 and the amplifier stage module 402.
In the case where the power supply mode is the second power supply mode, the port (1) and the port (2) are not connected, and at this time, the driver stage module 401 and the amplifier stage module 402 are supplied with power by different power supply modules, respectively. Such as shown in fig. 4: connecting port (1) to port (4) and port (2) to port (3) enables connection of driver stage module 401 to first power supply module 501 and connection of amplifier stage module 402 to second power supply module 502, with first voltage VCC1 provided by first power supply module 501 powering driver stage module 401 and second voltage VCC2 provided by second power supply module 502 powering amplifier stage module 402.
Alternatively, in the embodiment of the present application, the port (1) may be connected to the port (3), the port (2) may be connected to the port (4), so as to connect the driving stage module 401 to the second power supply module 502, and connect the amplifying stage module 402 to the first power supply module 501, where the second voltage VCC2 provided by the second power supply module 502 supplies power to the driving stage module 401, and the first voltage VCC1 provided by the first power supply module 501 supplies power to the amplifying stage module 402.
Referring to fig. 5, a schematic diagram of a second component structure of a power amplifier system according to an embodiment of the present application is shown. As shown in fig. 5, in this implementation, the amplification stage module 402 is connected to the second power supply module 502 in both the first power supply mode and the second power supply mode; the driver stage module 401 is connected to the second power supply module 502 in the first power supply mode, and is connected to the first power supply module 501 in the second power supply mode.
As shown in fig. 5, in the present embodiment, the second switch S2 is not disposed between the amplifying stage module 402 and the second power supply module 502, and in each power supply mode, the second power supply module 502 supplies power to the amplifying stage module 402, and the driving stage module 401 switches between the first power supply module 501 and the second power supply module 502 through the first switch S1. Since the power of the amplifying stage module 402 is generally greater than that of the driving stage module 401, the switch unit 403 is disposed on the driving stage module 401, on one hand, the influence of the switch unit 403 on signal amplification can be reduced, and on the other hand, compared with the switch disposed on the amplifying stage module 402, the switch disposed on the driving stage module 401 has a smaller current, so that the voltage of the switch is reduced, the voltage withstand is good, the area is small, and the voltage stability of the driving stage module 401 can be ensured.
In other embodiments, the second switch S2 may be still reserved, but the port (2) of the second switch S2 is always connected to the port (3). Such that the amplification stage module 402 is connected to the second power supply module 502 regardless of whether the power supply mode is the first power supply mode or the second power supply mode, the amplification stage module 402 is always powered by the second power supply module 502. For the driver-level module 401, its connection mode is adjusted in conjunction with the power mode: in the first power mode, port (1) is connected to port (3), and the second power module 502 simultaneously powers the driver stage module 401 and the amplifier stage module 402; in the second power mode, port (1) is connected to port (4) and the driver stage module 401 is powered by the first power module 501.
In another implementation, referring to fig. 6, a schematic diagram of a composition structure of a power amplifier system according to an embodiment of the present application is shown. As shown in fig. 6, in this implementation, the driver stage module 401 is connected to the first power supply module 501 in both the first power supply mode and the second power supply mode; the amplifier stage module 402 is connected to the first power supply module 501 in the first power supply mode and connected to the second power supply module 502 in the second power supply mode.
As shown in fig. 6, in the present embodiment, the first switch S1 is not disposed between the driving stage module 401 and the first power supply module 501, and in each power supply mode, the first power supply module 501 supplies power to the driving stage module 401, and the amplifying stage module 402 switches between the first power supply module 501 and the second power supply module 502 through the second switch S2.
In addition, in other embodiments, the first switch S1 may still be reserved, but the port (1) of the first switch S1 is always connected to the port (4). Such that the driver stage module 401 is connected to the first power module 501 regardless of whether the power mode is the first power mode or the second power mode, the first power module 501 always supplies power to the driver stage module 401. For the amplifier stage module 402, the connection mode is adjusted in conjunction with the power supply mode: in the first power mode, port (2) is connected to port (4), and the first power module 501 simultaneously powers the driver stage module 401 and the amplifier stage module 402; in the second power mode, port (2) is connected to port (3), and the amplifier stage module 402 is powered by the second power module 502.
In this way, as shown in fig. 5 and 6, in this embodiment, one of the driving stage module 401 and the amplifying stage module 402 may be fixedly connected to one power supply module, and the other may be connected to the corresponding power supply module by the switch unit 403 according to the power supply mode, so as to implement flexible control.
Referring to fig. 7, a schematic diagram of a composition structure of a power amplifier system according to an embodiment of the present application is shown. As shown in fig. 7, in some embodiments, the power amplifier system 50 further comprises a power supply module 503, and the power supply mode of the power amplifier system 50 further comprises a third power supply mode, wherein:
in the third power mode, the driver stage module 401 and/or the amplifier stage module 402 are connected to the power supply module 503 to supply power to the driver stage module 401 and/or the amplifier stage module 402 via the power supply module 503. Thus, in the case where power supply is required, power can be supplied directly by the power supply (i.e., the power supply module 503).
It should be noted that, in the embodiment of the present application, the first power supply module 501 and the second power supply module 502 are used to provide a variable voltage/current, and the power supply module 503 is used to provide a fixed voltage/current.

For the driver stage module 401, the first power module 501 always supplies power to the driver stage module 401 regardless of the power mode. For the amplification stage module 402, in the first power mode, the port (2) is connected to the port (4), so that the amplification stage module 402 is also powered by the first power module 501; in a second power mode, port (2) is connected to port (3) such that power is supplied to the amplifier stage module 402 by the second power module 502; in the third power mode, port (2) is connected to port (5) so that power is supplied to the amplifier stage module 402 by the power supply module 503.

As shown in fig. 10 or 11, in some embodiments, the power supply 60 includes a power module 503 in addition to the first power supply module 501 and the second power supply module 502, where the power module 503 is connected to the first power supply module 501 and the second power supply module 502. The power module 503 may be specifically a power management unit PMU, and thus, the power module 503 is denoted by PMU in fig. 10 and 11.
In one implementation, as shown in fig. 10, the first power supply module 501 and the second power supply module 502 are integrated within the same power management chip PMIC; alternatively, in another implementation, the first power supply module 501 and the second power supply module 502 are two power management chips PMIC, respectively, and thus, in fig. 11, the first power supply module 501 and the second power supply module 502 are denoted as PMIC1 and PMIC2, respectively. For the operation of the power supply module 503, reference may be made to the operation of the power management unit, and for the operation of the first power supply module 501 and the second power supply module 502, reference may be made to the operation of the PMIC, which will not be described in detail herein.

Taking the example of integrating the switch unit 403 into the amplifier 40, reference is made to fig. 12 to 15, which are schematic diagrams of the composition structure of the amplifier provided in some embodiments of the present application.

As shown in fig. 12 to 15, in some embodiments, the switch unit 403 is integrated in the amplifier 40, and at this time, the switching between the amplifier and the different modules can be achieved without integrating a switch in the PMIC, so that the PMIC stability is better, and the product service life is improved.
When a plurality of amplifiers are connected to one PMIC, the switching unit (or the change-over switch) may also cut off the switching unit and the bias power supply at the power supply end of the inactive amplifier, and may reduce the capacitive load on the PMIC as compared with the manner of cutting off the bias power supply to stop the operation of the amplifier, thereby reducing the influence of the inactive amplifier on the active amplifier.
That is, when the amplifier is stopped, the driving stage module 401 and/or the amplifying stage module 402 is disconnected from the power supply module, where the power supply module refers to the first power supply module 501, the second power supply module 502, or the power supply module 503 that performs power supply.
