ABSTRACT:
A plurality of substrate bias circuits (14, 16, and 18) are designed to provide a stable substrate reference potential for a variety of operating modes. Only one of the bias circuits is enabled by a control circuit (12) at any time for any operational mode. An on-demand boost bias circuit (16) is enabled whenever a level detector (20) indicates substrate bias has exceeded a predetermined limit during special operating modes such as burn-in or parallel test.
