Four-phase power clock generator for adiabatic logic circuits

Abstract

A circuit for a four-phase trapezoidal power clock generator for adiabatic logic circuits realised with a double-well 0.25 µm CMOS technology and external inductors is proposed. The circuit, at a frequency of 7 MHz which is within the optimum frequency range for adiabatic circuits realised with 0.25 µm CMOS technology, has a conversion efficiency higher than 80%, and is robust with respect to parameter variations.
