Abstract:
1. An on-chip impedance matching power amplifier comprises: transistor having a gate, a source, and a drain, wherein the gate is operably coupled to receive an input signal, and wherein the source is coupled to a first DC voltage potential; an inductor operably coupled to the drain of the transistor and to a second DC voltage potential; and capacitive divider operably coupled to the drain of the transistor and to the first DC voltage potential, wherein a tap of the capacitive divider provides an output of the on-chip impedance matching power amplifier, wherein capacitance of the capacitive divider and inductance of the inductor are tuned to provide a tank circuit for the on-chip impedance matching power amplifier and impedance matching with a load of the on-chip impedance matching power amplifier.
