摘要： A Doherty power amplifier (300) is provided that includes a main amplifier device (302) and an auxiliary amplifier device (304). The Doherty power amplifier further includes a phase compensation network (320a and/or 320m). The phase compensation network is configured to maintain a substantially constant phase of one of an output signal from the main amplifier device or an output signal from the auxiliary amplifier device across a range of input powers. The Doherty power amplifier further includes an impedance inverter (106) for power combining an output signal of the main amplifier device with an output signal of the auxiliary amplifier device.

摘要： A transconductance cell (100) is disclosed that includes a first transistor (101) and a second transistor (102). A regulator (107) regulates an average voltage in response to a reference voltage (150), where the average voltage corresponds to the average of a voltage at a bias terminal of the first transistor and a voltage at a bias terminal of the second transistor. A mixer including the transconductance cell is also disclosed. In the mixer, the transconductance cell receives a differential input voltage and produces a differential output current. The mixer also includes one or more switches that multiply the differential output current with an oscillator signal. A method is disclosed that includes measuring an average voltage of a voltage at a bias terminal of a first transistor and a voltage at a bias terminal of a second transistor and regulating the average voltage responsive to the measured average voltage and a reference voltage.
