Abstract
The present disclosure describes self-biasing radio frequency circuitry. In some aspects a radio frequency (RF) signal is amplified via a circuit having a first transistor configured to source current to an output of the circuit and a second transistor configured to sink current from the output of the circuit, and another signal is provided, without active circuitry, from the output of the circuit to a gate of the first transistor effective to bias a voltage at the output of the circuit. By so doing, the output of the circuit can be biased without active circuitry which can reduce design complexity of and substrate area consumed by the circuit.
