ABSTRACT:
Various voltage regulators and/or voltage regulation systems are disclosed. For example, a voltage regulation system that includes a source follower output is disclosed. The source follower output includes a transistor where the source of the transistor provides a baseline voltage to a regulated voltage output node. The voltage regulation system further includes a body damping circuit and a low speed feedback circuit. The body damping circuit is electrically coupled to the body of the transistor, and is operable to provide a rapid opposition to any voltage disturbance at the regulated voltage output node. The low speed feedback circuit is electrically coupled to the gate of the transistor, and is operable to return the regulated voltage output node to the baseline voltage.
