ABSTRACT:
An on-chip impedance matching includes a transistor and a tank circuit. The transistor is operably coupled to receive an input signal. The tank circuit is operably coupled to the transistor, wherein a tap of the tank circuit provides an output of the on-chip impedance matching power amplifier, wherein the tank circuit is tuned with respect to an antenna load of the on-chip impedance matching power amplifier.
