Learning Outcomes
This course aims to develop an understanding of the need for power management circuits in VLSI systems and familiarize students with various components of a power management system, particularly voltage regulators. By the end of the course, students should be able to design both linear (LDO) and switching regulators (dc-dc converter) according to specifications using behavioral and circuit-level simulators.
