ABSTRACT:
A speed governor for a microprocessor which prevents the operation above a selected frequency. Three resistors in a bridge network are switched capacitor "resistors" controlled by the input clocking signal. The value of the fourth resistor of the bridge is selected through connections to bonding pads. The bridge through a comparator disrupts the microprocessor's operation. The bondings also permit selection of an oscillator range and phase gap in the internal clocking signals.
