Abstract
A common (ground) of a low voltage regulator is connected to a virtual common (ground) of an integrated circuit device that is also connected to transistor sources but isolated from a true ground connected to the substrate of the integrated circuit device. The regulated output voltage from the low voltage regulator rises the same as the virtual ground voltage rises when back-biased sufficient to reduce leakage current to an acceptable level in a given process technology. Therefore, the output of the low voltage regulator will maintain a normal operating voltage for the logic during a power saving back-biased condition.
