Fully integrated transformer less floating gate driver for 3D power supply on chip

Abstract

Power supply on chip (power SoC) has been caught attentions because it can ultimately miniaturize the power supplies. To realize 3D power SoC which is fabricated using mass production process, we need to meet the various electrical requirements. Series and/or parallel connections is mentioned as good method. In such a situation, we previously proposed transformer less floating gate driver circuit using Schottky barrier diode (SBD). However, SBD is not suitable for integration. In this paper, we investigate the transformer less floating gate driver using MOS devices.
