Abstract (en)
[origin: EP0015342A1] A substrate bias regulator 11 useful for controlling a variable output oscillator 12 and/or a substrate bias voltage generator 13 ist provided to control the substrate voltage on a semiconductor chip 10. 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 16, 32 has its gate electroce connected to reference potential ground which tends to make the regulator independent of transistor thresholds.
