1. A circuit for monitoring and controlling the propagation delay time of signals passing through an integrated circuit, the integrated circuit being of the type in which propagation delay time varies with variations in the temperature of the integrated circuit, comprising:

  • temperature varying means on the integrated circuit for varying the temperature of the integrated circuit; and

    means for sensing propagation delay time and coupled to the temperature varying means for controlling the temperature varying means to selectively vary the temperature of the integrated circuit to control the propagation delay time.
