Abstract
A method for dynamically varying a threshold voltage of a complimentary metal oxide semiconductor (CMOS) includes providing a substrate pickup formed a semiconductor material type which is complimentary to the semiconductor material type of a well thereof, so as to define a diode. The diode is at least partially turned on, so as to increase the potential of a substrate of the complimentary metal oxide semiconductor and thus reduce the turn-on threshold voltage thereof. The turn-off threshold voltage is approximately unchanged.
