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： A proximity sensor system includes a touch-sensor pad with a sensor matrix array having a characteristic capacitance on horizontal and vertical conductors connected to sensor pads. The capacitance changes as a function of the proximity of an object or objects to the sensor matrix. The change in capacitance of each node in both the X and Y directions of the matrix due to the approach of an object is converted to a set of voltages in the X and Y directions. These voltages are processed by circuitry to develop electrical signals representative of the centroid of the profile of the object, i.e, its position in the X and Y dimensions. Noise reduction and background level setting techniques inherently available in the architecture are employed. A conductive paintbrush-type stylus is used to produce paint-like strokes on a display associated with the touch-sensor pad.

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 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.

摘要： 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.

摘要： An electronic circuit is disclosed having a sample/hold amplifier connected to an adaptive amplifier. A plurality of such electronic circuits may be configured in an array of rows and columns. An input voltage vector may be compared with an analog voltage vector stored in a row or column of the array and the stored vector closest to the applied input vector may be identified and further processed. The stored analog value may be read out of the synapse by applying a voltage to a read line. An array of the readable synapses may be provided and used in conjunction with a dummy synapse to compensate for an error offset introduced by the operating characteristics of the synapses.
