Abstract

A 12.5 mW, 500 MHz class DE power inverter was designed and simulated as an inverter part of dc-dc converters to realize a fully integrated switching power supply using a 1.2 mum CMOS process. A 20 nH spiral inductor was used in the resonant circuit. The class DE inverter requires lower inductance than PWM buck converter. Soft switching operation enables high conversion efficiency at high operating frequencies. The class DE inverter can be an excellent candidate for on-chip switching converters because of very high efficiency, smaller passive elements, and low peak switch voltage
