Abstract
Described herein is an apparatus and system of a low-impedance reference voltage generator. The apparatus comprises: a voltage-control loop including a first transistor to provide an output voltage; and a current-control loop to sense current through the first transistor, relative to a reference current. The node having the output voltage is a low-impedance node.
