Abstract

A numerical method for designing a class E power amplifier with a non-linear transistor output capacitance is presented. By matching the fundamental and second harmonic impedances of the output network, the method can be extended for designing a class E power amplifier with both non-linear transistor output capacitance and finite DC-feed inductance. A design example of 0.4 W 1.4 V class E power amplifier at 1 GHz with AMS 0.6 μm BSIM.3v3 CMOS model is used to validate the method
