Abstract: A circuit for stabilizing the temperature of a microcircuit substrate at a constant value includes a sensor in the form of a resistance bridge comprised of both positive and negative temperature coefficient resistors, a control circuit connected across a first set of bridge diagonal points which is powered by the bridge unbalance voltage across these points, and a heater circuit which optionally includes a current limiting device and which is connected across a second set of bridge diagonal points, the heater circuit being controlled by action of the control circuit.
