Abstract:
1. A clock based voltage deviation detector comprising: a pulse module having a pulse input for receiving a clock signal and a pulse output for outputting a stream of reset pulses, wherein said pulse module includes, an indicator module having a first indicator input for receiving an input signal, a second indicator input for receiving a reference voltage, a third indicator input communicatively coupled to said pulse output of said pulse module and an indicator output for outputting a pass/fail indicator signal as a function of said stream of reset pulses and a difference between said input signal and said reference voltage; and a correlation module having a first correlation input for receiving said clock signal, a second correlation input communicatively coupled to said indicator output of said indicator module, wherein an event of said pass/fail indicator signal is correlated to a specific period of said clock signal at which said event occurred.
