Abstract:
An inverting single device with operating characteristics similar to dual device seriesed N and P-Channel MOSFETS CMOS systems comprising two oppositely facing electrically interconnected rectifying diodes in semiconductor, wherein a forward direction of rectification of each of said electrically interconnected rectifying diodes changes depending upon what doping type, N or P, be it metallurgically or field induced, is present in the semiconductor, said inverting single device with operating characteristics similar to dual device seriesed N and P-Channel MOSFETS CMOS systems further comprising gate means for field inducing effective doping type in said semiconductor, said gate means being set off from said semiconductor by insulator and each of said electrically interconnected rectifying diodes having an electrically non-interconnected terminal; and wherein, in use, the electrically non-interconnected terminals of the oppositely facing rectifying diodes are held at different voltages, and a voltage between said applied different voltages, inclusive, is monitored at the electrical interconnection between said two oppositely facing rectifying diodes, which monitored voltage responds inversely to applied gate voltage, said monitored voltage being essentially electrically isolated from said gate voltage and appearing at said electrical interconnection between said two oppositely facing rectifying diodes primarily through the rectifying diode which is caused to be forward biased as a result of semiconductor doping type metallurgically present or field induced by said applied gate voltage;the basis of operation of said inverting single device with operating characteristics similar to dual device seriesed N and P-Channel MOSFETS CMOS systems being that said two oppositely facing electrically interconnected rectifying diodes are each comprised of at least one material that forms a rectifying junction to semiconductor when it is doped either N or P-type by either metallurgical or field induced means.
