<p>In a conventional gated clock generating circuit, different signal delay times are produced depending on the arrangement of interconnection of circuit elements, often causing glitches. To avoid this, a gated clock generating circuit of the invention has a circuit that generates a first gate signal having inversion points synchronous with edges of a continuously pulsating clock signal, a circuit that generates a second gate signal deviated by half the period of the clock signal relative to the first gate signal, and a circuit that turns on and off the output of the clock signal in accordance with the first and second gate signals. Even when inversion points of the first or second gate signal deviate from edges of the clock signal, no glitches result. <IMAGE></p> |
