ABSTRACT:
In accordance with the present invention, a heater is included on an integrated circuit, together with a circuit for controlling the heater to selectively heat the integrated circuit and control the propagation delay time of signals passing through the integrated circuit. In a specific form of the invention, the propagation delay time of signals passing through at least a portion of an integrated circuit is measured and compared with a reference propagation delay time. The heater is controlled to increase the heat it produces when the measured propagation delay time is less than the reference propagation delay time. In addition, the heater is controlled to decrease the heat it provides when the measured propagation delay time is greater than the reference propagation delay time.
