Abstract
An 'on chip' substrate bias generator circuit to automatically compensate for threshold variations of devices that form a MOS circuit. The substrate bias generator includes a voltage doubler (or trippler) to develop a wide range of negative bias voltage to be fed back via the substrate to the MOS circuit to provide uniform bias control of the circuit devices.
