Abstract

A de-glitch circuit is provided. The de-glitch circuit uses a clock signal which is provided from internal of an integrated circuit. The clock signal is used to separate a glitch from an input-signal when the glitch appeared in the edge of the input-signal. This de-glitch circuit comprises an edge signal generator, an OR gate, an AND gate, a selecting apparatus, a first flip-flop and a second flip-flop. The de-glitch circuit uses above various components specific connection relations and function. Thus, the de-glitch circuit is able to filter a glitch which is smaller than a half of the clock signal period.
