摘要： A circuit for use as a channel of a minimum selector and subtractor circuit includes a P-Channel MOS transistor having a gate connected to an input node, a source connected to the output of a current source, and a drain connected to a fixed voltage source. The source of the P-Channel transistor is connectable to a common conductive line through a first switch. The source of the P-Channel transistor is also connected to the non-inverting input of a transconductance amplifier. The inverting input of the transconductance amplifier is connected to a first plate of a capacitor. The second plate of the capacitor is connected to a fixed voltage source such as ground. The output of the transconductance amplifier is connectable to its inverting input through a second switch. The output of the transconductance amplifier forms the output of the minimum selector and subtractor circuit. A plurality of individual channel circuits may all be connected to the common conductive line. The input nodes of the individual channel circuits are each individually connected to a different one of a plurality of analog input lines. The minimum selector and subtractor circuit determines the minimum analog value appearing on the plurality of lines and subtracts that value from the input values on all of the input lines. A maximum selector and subtractor circuit is formed by reversing transistor types.

摘要： An integrated circuit amplifier having a random input offset voltage is adaptable such that the input offset voltage may be cancelled out. An inverting input node is a floating input node and is coupled to a source of input signal by a first capacitor. A second capacitor is connected between the output of the amplifier and the floating node. An ultraviolet window above the second capacitor allows the floating node to be charged, by the application of ultraviolet light, to a voltage which effectively cancels the input offset voltage. The ultraviolet window and capacitor electrodes are arranged such that the ultraviolet light may strike only the desired areas of the structure.

摘要： 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.
