This paper presents the design of a multiphase self-sensing clock generator and its application in a hybrid digital pulse-width modulator（DPWM）.Based on a voltage controlled ring oscillator（VCO）,the clock generator has its control voltage generated from a self-sensing circuit which uses a new enhanced circuit to compensate temperature and process variation.Its application in a hybrid DPWM could effectively reduce the required bits of counter.Simulation results show its frequency reaches 157.7MHz while the worst variation,across a temperature range of 0℃ to 100℃ under each process corner,is only ±5.7%.Besides,it reduces the required clock frequency for a 6-bit hybrid DPWM from 2.52GHz to only 157.7MHz.
