    Abstract: A power amplifier circuit includes a current generator and a current mirror driver. The current generator has a first input connected to a first voltage supply and an output configured to generate a first current. The current generator includes a first transistor, a second transistor, a first resistor and a second resistor. The first transistor has an emitter connected to ground. The second transistor has a base connected to a base of the first transistor and an emitter connected to ground. The first resistor is connected between the first voltage supply and a collector of the first transistor. The second resistor is connected between the first voltage supply and a collector of the second transistor. The current mirror drive has a first input connected to the output of the current generator to receive the first current and an output configured to generate a second current.

    Abstract: The present disclosure relates to a power amplifier circuit. The power amplifier circuit includes a voltage-controlled current source and a current mirror. The voltage-controlled current source is configured to receive a first voltage and to generate a first current. The current mirror is connected to the voltage-controlled current source and to generate a second current in response to the first current. The second current continuously changes from 0 mA to about 120 mA as the first voltage continuously changes from 0 V to about 1 V.

    Abstract: A power amplifier circuit includes a first transistor, a second transistor and a bias circuit. The first transistor has a base configured to receive a first signal. The second transistor has an emitter connecting to a collector of the first transistor and a collector configured to output a second signal. The bias circuit is coupled to the first transistor and the second transistor. The bias circuit is configured to provide a direct current (DC) voltage at the collector of the second transistor about twice a DC voltage at the collector of the first transistor. The bias circuit is configured to provide an alternating current (AC) or radio frequency (RF) voltage at the collector of the second transistor about twice an AC or RF voltage at the collector of the first transistor.
