    摘要

    An auto-biasing cascode class-E PA which can compensate the Vdd/AM and Vdd/PM distortion resulting from supply modulation has been proposed. The output voltage of auto-biasing control circuit is generated and varied linearly with PA's supply voltage so that the cascode transistor is degenerated into a resistance and the PA's nonlinear distortion can be compensated. The simulation result shows that the distortion is compensated evidently and the system cosimulation demonstrated that system EVM can be improved from -17 to -19dB. Also, the drain efficiency of the PA can be improved 15% within small supply voltage range.
