Abstract
An adaptive-Vth CMOS/SOI DC-DC converter scheme, which consists of a low-Vth charge-pump circuit and a high-Vth DC-DC converter, and enables to operate at 0.3-V, is proposed. The low-Vth circuit starts to boost a small input voltage and generates output power. And then the high-Vth converter continues the boosting operation by using the power of the low-Vth circuit. If once the high-Vth converter starts, the low-Vth circuit automatically stops the boosting operation. We fabricated the adaptive-Vth DC-DC converter with a 0.8-mum FD-SOI process and verified the converter has a conversion efficiency of more than 80% at an input voltage of 0.3 V
