Abstract
As power supply managements become more important than before, supplying a stable system voltage is becoming more and more critical. In this study we propose to use the advantage of weak inversion region of MOS transistors. Analog system, which uses weak inversion region, could work in low voltage environment and reduce power consumption. The proposed buck-converter in weak inversion region of MOS transistor has been verified by silicon chip.
