ABSTRACT:
A temperature compensation circuit (FIG. 5a) has a controlled temperature compensated voltage drop across R1. A Schottky diode D1 is connected to the base of Q1 through resistor R1. The temperature coefficients of the base-emitter junction of Q1 and the diode D1 have a predetermined differential, preferably none. The forward voltage drop across D1 and the base-emitter junction are different, thereby establishing a controlled current through resistor R1 that is independent of temperature.
