Abstract
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 157.7 MHz while the worst variation, across a temperature range of 0degC to 100 degC under each process corner, is only plusmn5.7%. Besides, it reduces the required clock frequency for a 6-bit hybrid DPWM from 2.52 GHz to only 157.7 MHz.
