ABSTRACT:
A substrate bias voltage regulator (10) is disclosed having a voltage divider (22) for generating a reference voltage, a low gain stage (24) for developing a drive voltage independent of the supply voltage (V.sub.cc) and for driving a current source/mirror circuit (26). The current source/mirror circuit (26) operates in conjunction with a current sink circuit (30) for providing a logic output of the regulator (10) for controlling a substrate charge pump circuit (18). Connected to the current sink circuit (30) is a compensation circuit (32) for adjusting the drive to the current sink circuit (30) in response to transistor threshold voltage and temperature considerations.
