Abstract:
According to the invention a well-switching arrangement, with a semiconductor circuit including a switch having an input terminal, an output terminal and a body region and at least one comparator having a first input coupled to at least one of the terminals and a second input coupled to a positive voltage rail, and logic coupled to an output of the comparator and responsive to the output to selectively couple the body-well region to one of the terminals or to the positive voltage rail.
