Abstract

This paper describes the implementation of a novel and highly versatile digital pulse width modulator (DPWM) - probably the most critical component in any digitally controlled switching power converter. Its new architecture, composed of a delay-locked loop (DLL) and programmable DPWM module, allows the generation of high resolution, high switching frequency (f_sw) PWM signals. The DPWM IC was designed using a standard 0.35-μm CMOS process and supports switching frequencies beyond 15 MHz.
