Abstract

The resistive coupled matrix circuit has n columns on which are provided input signals via n column selectors, and m lines connected to m line selectors via m line signal sampling circuits. Each of these m line signal sampling circuits is made up of an operational amplifier (01) whose non inverting input is earthed, whilst the inversing input is connected to the line corresponding to the matrix circuit and to a resistance (Rf1) whose other end is connected to the output of the operational amplifier. These sampling circuits suppress the parasitic currents in the matrix circuit.
