Abstract:
Circuits and methods are provided for facilitating transitioning of a digital circuit from backgate biased standby mode to active mode. The digital circuit includes a semiconductor substrate, multiple n-channel transistors disposed at least partially in one or more p-type wells in the semiconductor substrate, multiple p-channel transistors disposed at least partially in one or more n-type wells in the semiconductor substrate, and a backgate control circuit. The backgate control circuit is electrically coupled to the p-type well(s) and to the n-type well(s) to facilitate transitioning of the multiple n-channel transistors and the multiple p-channel transistors from backgate biased standby mode to active mode by automatically shunting charge from the n-type well(s) to the p-type well(s) until a well voltage threshold is reached indicative of a completed transition of the transistors from backgate biased standby mode to active mode.
