Investigation of fully integrated power stage for piezoelectric DC-DC converters

Abstract

This work explores the potential of piezoelectric DC-DC converters as a viable alternative to inductive-based converters. Their exceptional frequency-scale property and planar shape make them highly promising. However, for seamless integration, it is crucial to incorporate the power stage into a single chip. By utilizing the most favorable piezoelectric material, namely LNO in thickness vibration mode, this study examines the achievable performance metrics such as efficiency, power density, and silicon surface area using a fully integrated power stage within a classical BCD technology.
