CMOS winner-take all circuit with offset adaptation
 An adaptable MOS winner take all circuit includes a plurality of adaptable current mirrors. Each adaptable current mirror includes a floating node onto which and from which electrons may be transported by control signals and electrical semiconductor structures. Electrons may be placed onto and removed from a floating node associated with at least one MOS insulated gate field effect transistor, usually the gate of the transistor, in an analog manner, by application of first and second electrical control signals. A first electrical control signal controls the injection of electrons onto the floating node from an electron injection structure and the second electrical control signal controls the removal of electrons from the floating node by an electron removal structure.
