Abstract
This paper investigates the design curves of the class DE amplifier with nonlinear shunt capacitances for any output Q and any grading coefficient m of the diode junction in MOSFET. The design curves are derived by the numerical calculation. It is clarified that the nonlinearities of shunt capacitances affect the design curves of the class DE amplifier, especially, for low output Q. The waveforms from SPICE denote the validity of the design curves.
