Abstract
A substrate bias regulator useful for controlling a variable output oscillator and/or a substrate bias voltage generator is provided to control the substrate voltage on a semiconductor chip. A series of field effect transistors are arranged in a manner to sense the substrate voltage and to provide an output to regulate the substrate voltage. One of the series field effect transistors has its gate electrode connected to reference potential ground which tends to make the regulator independent of transistor thresholds.
