ABSTRACT:
An integrated circuit includes: a comparator coupled in a configuration to compare two voltages. One of the two voltages includes a semiconductor junction voltage drop. The other of the two voltages includes a voltage signal, X V.sub.t, where V.sub.t is a thermal voltage and X includes a selected signal value, which modulates the thermal voltage. The configuration includes a feedback path to vary X until X V.sub.t approximately equals the voltage including the semiconductor junction voltage drop.
