Abstract

The paper presents a purely-digital architecture and an IC implementation of a PWM controller based on vendor´s standard cells library alone. A full design flow is presented and explained. The architecture and configurations of the key building blocks are designed to meet the requirements of a complete digital implementation. The PWM controller is realized via Cadence tools in Tower Jazz 0.18μm power management (TS18PM) platform. A design example based on a buck converter operating at the switching frequency of 2.5 MHz is presented. Post-layout simulations results are shown to validate the design approach.
