Abstract

This paper proposes a novel method for ripple cancellation in multi-phase converters. Unlike the conventional multi-phase converter, the proposed topology can cancel the ripple irrespective of the duty ratios. The proposed topology is designed to give 3.3V output for wide supply range of 4.5 to 18V and load range of 0 to 3A in AMS 0.35um high-voltage CMOS process. Transistor level simulation results validate that the proposed method can reduce the ripple by 80% in a multi-phase converter. Cancelling the current ripple at the output allows the inductors and capacitors to be sized much smaller compared to the state of the art reported designs.
