ABSTRACT:
An integrated circuit and method includes a substrate bias voltage control circuit formed on a common substrate therewith for ensuring that the substrate has a voltage applied thereto while a semiconductor device on the substrate has a supply voltage applied thereto which includes means for providing sources of bias and supply voltages to the substrate with means for firstly coupling the bias voltage to the substrate when the bias voltage is present and means for secondly coupling the supply voltage to the substrate when the bias voltage is not present.
