ABSTRACT:
The clock based voltage deviation detector of the present invention includes a pulse module, an indicator module and a correlation module. The pulse module generates a stream of reset pulses as a function of a clock signal. The indicator module generates a pass/fail indicator signal as a function of the reset pulse stream and a difference between an input signal and a reference voltage. The correlation module correlates an event (e.g., overvoltage or undervoltage) of the pass/fail indicator signal with a period of the clock signal at which the event occurred.
