Abstract
This paper presents an all-digital pulse width modulator (PWM) for application in integrated DC-DC converters. Based on a multi-phase clock signal a PWM resolution of 62.5ps is achieved, resulting in up to 16-Bit PWM resolution at 4096ns period. The PWM signal duty cycle and period can be arbitrarily changed within a single cycle which allow efficient alldigital implementation of spread spectrum clocking schemes. The circuit has been implemented in 28nm SLP CMOS technology. It consumes 0.3mW when operating from a 1.0V supply.
