Abstract
A digital glitch filter for filtering glitches in an input signal includes first and second flip-flops and a synchronizer. The synchronizer includes third and fourth flip-flops. A glitch prone input signal is provided to the first and second flip-flops. Additionally, an input clock signal is provided to the first and second flip-flops and the synchronizer. A glitch occurring in the input signal toggles the first and second flip-flops between transmitting and non-transmitting states and first and second intermediate signals are generated. The synchronizer synchronizes the first and second intermediate signals with the input clock signal to generate a filtered output signal.
