1. A circuit responsive to a plurality of correlation signals comprising:

  • a correlation circuit including a plurality of transistors having their current paths connected in parallel between a first voltage source and a first common lead, and having their control electrodes responsive to said correlation signals,a first load transistor having its current path coupled between said first common lead and a second voltage source, said first load transistor having a control electrode; and

    a compensating circuit coupled to the control electrode of said first load transistor for controlling the resistance of said first load transistor to provide a substantially constant voltage step on said common lead for each parallel transistor biased into conduction.
