1. A method comprising:

  • amplifying a radio frequency (RF) signal via a circuit having a first transistor configured to source current from a power source to an output of the circuit based on the RF signal and a second transistor configured to sink current from the output of the circuit to a current sink based on the RF signal; and

    providing, without active circuitry, another signal from the output of the circuit to a gate of the first transistor effective to bias a voltage at the output of the circuit.
