Modeling of digitally controlled voltage regulator modules

Abstract

This paper proposed small signal models of digital VRMs. At first, the ADC's conversion delay and digital compensator's calculation delay are neglected. The focus is placed on the small signal model of the current sampling and the DPWM unit. It is shown that even with a “fast” controller, the current sampling and DPWM will still introduce some… (More)
