Abstract

Digitally controlled DC-DC converters enable design portability as well as reconfigurable compensation and control schemes. Digital controllers are also resistant to process and temperature variations making them attractive for SoC applications. The main building blocks of a digital controller for integrated switchmode converters are the feedback ADC that digitizes the error signal, the digital compensator, and the digital PWM generator (DPWM). The ADC and DPWM blocks are typically the most challenging circuits to design in terms of power consumption, complexity, and area.
