ABSTRACT:
An FET switch comprising a single or parallel opposite polarity FETS is illustrated with wells that are driven from internal power rails. The internal power rails are logically coupled by other driving FET switches to, in one case, the higher of a positive power supply or signal level wherein the well of the PMOS FET switch will not allow the drain/source to well diode to be forward biased. In a second case, a second power rail is logically coupled to the lower of either and input signal or ground, wherein the well of the NMOS FET will not allow the drain/source to well diode to be forward biased.
