Referring to fig. 1 and 2, a power detection circuit 100 according to an embodiment of the present invention includes an envelope amplifier circuit 11 and a plurality of current proportional amplifying circuits 12.
The input ends of the current proportional amplifying circuits 12 are connected to a radio frequency input signal RFin, the output ends of the current proportional amplifying circuits 12 are connected to the input end of the envelope amplifying circuit 11 in parallel, and the starting voltages of at least two current proportional amplifying circuits 12 are different from each other, so that the at least two current proportional amplifying circuits 12 are started in sequence along with the gradual increase of the radio frequency input signal RFin, and each current proportional amplifying circuit 12 amplifies the radio frequency input signal RFin after starting and outputs a current amplified signal RF. The envelope amplifier circuit 11 is configured to convert the current amplified signal into a voltage value Vout and output the voltage value Vout, thereby realizing a power detection function. Thus, in the power detection circuit 100 of the present invention, the plurality of current proportional amplifying circuits 12 are sequentially turned on with the gradual increase of the radio frequency input signal RFin, so that the purpose of widening the power detection range can be achieved.
In some embodiments of the present invention, the starting voltages of all the current proportional amplifying circuits 12 are different, so that all the current proportional amplifying circuits 12 start sequentially as the radio frequency input signal RFin increases gradually.
It will be appreciated that the input terminals of all the current scaling circuits 12 are connected to the input signal RFin, so that all the current scaling circuits 12 are connected in parallel with the rf input signal RFin, and the term "sequentially start" as used herein does not mean that the plurality of current scaling circuits are sequentially started according to the arrangement sequence of fig. 1, but means that the plurality of current scaling circuits are sequentially started according to the arrangement relation from the small row to the large row of the starting voltage, the starting voltage is small, and the starting voltage is large, and then the starting voltage is large.
The current proportional amplifying circuit 12 includes a first transistor Q1, a second transistor Q2, a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, and a first capacitor C1.
One end of the first resistor R1 is an input end of the current proportional amplifying circuit 12, and is used for inputting the radio frequency input signal RFin, and the other end of the first resistor R1 is connected with the collector of the first transistor Q1 through the first capacitor C1, that is, the collector of the first transistor Q1 is configured to receive the detected radio frequency input signal RFin.
The emitters of the first transistor Q1 and the second transistor Q2 are grounded, the base electrode of the first transistor Q1 is connected with the base electrode of the second transistor Q2 through the fourth resistor R4, the collector electrode of the first transistor Q1 is connected with the first voltage source Vcc1 through the second resistor R2, the third resistor R3 is connected between the collector electrode and the base electrode of the first transistor Q1, the collector electrode of the second transistor Q2 is connected with the first voltage source Vcc1 through the fifth resistor R5, the collector electrode of the second transistor Q2 is the output end of the current proportional amplifying circuit 12, and is connected with the input end of the envelope amplifier circuit 11.

In the embodiment of the present invention, the first resistor R1 and the first capacitor C1 are connected in series to the collector of the first transistor Q1, and may be used as a tap network, and coupled to the current proportional circuit structure in a direction, where the values of the first resistor R1 and the first capacitor C1 may be set according to the tap rate, so as to maintain the performance of the detected power amplifier.
Further, the values of the first capacitances C1 of the current proportional amplifying circuits 12 are different, so that the starting voltages of the current proportional amplifying circuits 12 are different. The starting voltage refers to the load voltage of the serial branch where the first capacitor C1 is located, and can be understood as the starting voltage of the first transistor Q1 and the second transistor Q2, different load voltages determine the on states of the transistors in the current proportional amplifying circuit 12, the load voltage is used for starting the transistors in the current proportional amplifying circuit 12, and the magnitude of each load voltage is related to the magnitude of the value of the first capacitor C1 in the tap network, so that by setting the values of the different first capacitors C1, the load voltages of the current proportional amplifying circuits 12 can be different, and the on states of the corresponding transistors are different. Wherein, the larger the first capacitor C1, the larger the load voltage.
When the radio frequency input signal RFin is gradually increased, the voltage of the first capacitor C1 is increased, and the circuit proportional amplifying circuits connected with the first capacitor C1 are in the states of opening, linear region and saturation region in sequence, so that the plurality of current proportional amplifying circuits 12 can keep linear relation with the size of the RFin signal, a power detection function in a wide power range is realized, and the linearity of detection power and output voltage is improved.
The second resistor R2 and the fifth resistor R5 are used as voltage dividing resistors of the collectors of the first transistor Q1 and the second transistor Q2, respectively, and can be used to adjust the collector voltages of the two transistors, that is, the collector voltages of the corresponding transistors can be respectively made different by setting the second resistor R2 with different resistance values and the fifth resistor R5 with different resistance values. The third resistor R3 and the fourth resistor R4 can adjust the collector currents of the first transistor Q1 and the second transistor Q2, that is, change the current amplified signal RF output by the current scaling circuit 12.
Further, the current proportional amplifying circuit 12 further includes a second capacitor C2. One end of the second capacitor C2 is connected to the base of the second transistor Q2, and the other end of the second capacitor C2 is grounded.

Therefore, in the present embodiment, the base of the third transistor Q3 receives the current output signals RF from the three current proportional amplifying circuits 12, and when the plurality of current proportional amplifying circuits 12 are turned on in time, the voltage Vout output by the envelope amplifier circuit 11 also changes. The second voltage source Vcc2 is used to provide a voltage greater than the amplitude of the current amplified signal RF, so the third transistor Q3 acts as a variable gain envelope amplifier, effectively amplifying the three current output signals RF received. The parallel connection of the sixth resistor R6 and the third capacitor C3 forms a low-pass impedance filter that converts the envelope of the output signal of the base of the third transistor Q3 from current to voltage, while the radio frequency component is split into a seventh resistor R7.
Further, the envelope amplifier circuit 11 further includes a first diode D1, a second diode D2, and a third diode D3.
