Fundamentals of Fully-Integrated Voltage Regulators Video

Abstract: Fully integrated voltage regulators (FIVRs) enable fast dynamic voltage and frequency scaling for energy-efficient high-performance digital systems. This tutorial will cover the fundamentals of low-dropout regulators (LDOs), as well as switched-capacitor (SC) and inductor-based DC-DC converters. Emphasis will be put on design considerations of analog/digital/mixed control, PID control for FIVR, resonant SC, and hybrid DC-DC converters. Last but not least, we will have a brief review of distributed FIVR designs.
