Abstract

See full text

An adaptable current mirror includes first and second MOS transistors. The first MOS transistor has its gate connected to its drain. A MOS capacitor structure is connected in series between the gate of the first MOS transistor and the gate of the second MOS transistor. Electrons may be placed onto and removed in an analog manner from a floating node associated with the second MOS transistor, usually the gate of the transistor, 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. A plurality of adaptable current mirrors communicating with a plurality of current-carrying lines may be employed for indicating the output of the one of the plurality of current-carrying lines through which the most current is flowing.
