Abstract
This paper describes a low voltage, low-power CMOS buck DC/DC converter, which has a simple common-gate current sensing circuit. It consumes low power because it includes less transistors than other converters which use operational amplifiers for current sensing. The designed DC-DC converter is fabricated in a 0.18um CMOS technology. A maximum efficiency of 88% has been obtained with the proposed circuit. It has
