Abstract
A speed governor for an integrated circuit which prevents the operation of the integrated circuit above a selected frequency. The speed governor generates a frequency reference and compares the frequency reference to the frequency of the external clock signal that clocks the integrated circuit. As a result of the comparison, if the frequency of the input clock signal is greater than the frequency reference then operation of the integrated circuit is disrupted.
