Transformer-less floating gate driver for 3D power SoC

Power supply on chip (power-SoC) has been caught attentions because ultimately miniaturize the power supplies. Especially, the 3D power-SoC is attractive and is fabricated using LSI and MEMS process. It is important to meet the various electrical requirements for expanding applications because they are fabricated using mass production process. In such situations, series and/or parallel connections of them is attractive. However, we generally use transformers as power supplies for floating gate driver circuits when we connect DC-DC converters series. Transformers are not suitable for power-SoC because they disturb miniaturization. In this paper, we propose a transformer-less floating gate driver circuit for 3D power SoC.The IEEE International 3D Systems Integration Conference (3DIC 2019), October 8-10, 2019, Sendai, Japa

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

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.2021 IEEE International 3D Systems Integration Conference (3DIC 2021), November 15-18, 2021 North Carolina, US
