Abstract
We present a low dropout voltage regulator which uses a regulated replica in the loop in order to achieve small area, excellent power supply rejection over a wide frequency range, and high loop stability. The regulated replica provides accurate matching of the gm/gds ratio in the current source transistors for the replica and the load path. Power supply rejection of >22 dB was measured up to 1 GHz for a circuit operating at 0.8 V from a 1.0 V supply.
