Abstract

In this paper, a buck DC-DC converter is presented that is capable of operation under variable input battery voltage ranging from 3.5V to 6V. The proposed converter is based on a new design technique using an adaptive biasing circuit for cascode power stage. The biasing circuit changes its configuration when the battery voltage drops down to 4.5V. The converter is implemented in 45-nm CMOS technology; it was simulated and its operation was verified at an output power of 200mW where it achieves a maximum power conversion efficiency of 81% for an output voltage of 1.25V.
