ABSTRACT:
A dynamic signal appearing across the output of a logic circuit is converted into a static signal using a dynamic-to-static conversion method which minimizes glitching in the static output. A pull-down device, operatively coupled between an output node and a ground, which is closed while an input node is at a precharge potential and is open while the input node is at a ground potential, and a pull-up device, operatively coupled between a source voltage and the output node, is closed while the input node is at the ground potential and is open while the input node is at the precharge potential. Also, a pull-down path shutoff device, operatively coupled between the output node and the ground in series with the pull-down device, is closed during each first phase of a clock signal and is open during each second phase of the clock signal, and an activation device, operatively coupled between the output node and the series connection of the pull-down device and the pull-down shutoff device, is closed during each first delayed phase of a delayed clock signal and is open during each second delayed phase of the delayed clock signal.
