TEG-Based Power Management Designs and Characterizations

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

This chapter presents a detailed characterization of several PMUs that target thermal energy harvesting wearable device. Several TEG-based PMU design options are proposed to select the appropriate option according to the blocks’ requirements within the device given in Fig. 1.12. In this chapter, three various TEG-based PMUs are characterized: design 1: switched inductor (SI) boost converter followed by a switched capacitor (SC) voltage regulator, design 2: SI followed by LDO regulator, and design 3: SI followed by two voltage regulators in series of SC and LDO. The characterization is based on silicon measurements where the TEG-based PMUs are fabricated in a single chip in 65 nm CMOS. Power efficiency, area, and voltage ripple have been measured for different PMU topologies.
