Abstract
A complementary metal oxide semiconductor (CMOS) voltage regulator for low headroom applications includes a differential input common mode range amplifier. The differential input common mode range amplifier is formed by a plurality of CMOS transistors. A source follower CMOS transistor is coupled to an output of the differential input common mode range amplifier for providing an output of the CMOS voltage regulator. A current source is coupled to the differential input common mode range amplifier for maintaining a bias current through the differential input common mode range amplifier.
