Full-wave AC-DC converter in CMOS 0.18 micron for vibration electromagnetic energy harvest

Abstract

This paper presents the design and implementation of full-wave AC-DC converter in 0.18 micron CMOS technology. Five sample voltages were taken from vibration electromagnetic harvester technology (VEHT) and simulated in three operating temperatures of 0, 25, and 70 degrees Celsius. The simulation results yielded: a maximum average power efficiency of 95.02% at 0°C 95.61% at 25°C, and 91.05% at 70°C; and an average regulation percentage of 10.45% at 0°C, 24.91% at 25°C, and 10.15% at 70°C.
