Matrix circuit

Abstract

Abstract PURPOSE:To eliminate the fluctuation of the output DC potential with a simple circuit constitution, by providing a voltage transducers between each output of a current converting means and the reference potential. CONSTITUTION:A current source 1 receives the application of the subsignal between the control electrodes and produces the current corresponding to a pair of differential transistors (TRs)Q1 and Q2 plus the main signal to supply the current to these TRQ1 and Q2. Current Miller circuits 2 and 3 convert each of the currents flowing to the TRQ1 and Q2 with a constant ratio and then deliver the converted currents. Branching means 4 and 5 branch the DC current in the output of the circuits 2 and 3 respectively. Thus the AC current in each output of the circuits 2 and 3 is led out in the form of each output of the right and left channel signals.
