Abstract
A temperature control system having: a resistor formed in a region of a semiconductor, such resistor having a pair of spaced electrodes in ohmic contact with the semiconductor; at least one device formed in another region of the semiconductor thermally proximate the resistor formed region, such device generating heat in the semiconductor; and circuitry, including a reference connected to one of the pair of electrodes, for operating the resistor in saturation and for sensing variation in the resistor in response to the heat generated by the device and for controlling the heat generated by the device in the semiconductor in response to the sensed variation.
