DIGITALLY CONTROLLED PULSE WIDTH ADJUSTING CIRCUIT

摘要

A circuit selectively adjusts the width of an input pulse. The circuit comprises two stages. The first stage delays a leading edge of the input pulse with respect to a trailing edge of the input pulse in accordance with a first control input. The second stage delays the trailing edge of the input pulse with respect to the leading edge of the input pulse in accordance with a second control input. The input pulse width is adjusted in accordance with a difference between the delay of the leading edge and the delay of the trailing edge.
