  • Publication number: 20090189644
    Abstract: A short pulse rejection circuit may include an edge detector, a filter circuit, a comparison circuit, and a gating circuit. The edge detector may delay an input signal to generate a delayed input signal, and detect an edge of the input signal to generate an edge detection signal. The filter circuit may perform a low pass filtering on the edge detection signal to generate a first signal. The comparison circuit may compare the first signal with a reference voltage. The gating circuit may gate the delayed input signal based on an output signal of the comparison circuit. Therefore, the short pulse rejection circuit may have a sufficient setup/hold time margin of a flip-flop, and may sample an input signal even when a state of the input signal does not change during an initial operation.
