ABSTRACT:
An op-amp feedback arrangement is used to provide non-skewed clock pulses from a source of skewed clock pulses. Any skew in the clock-in pulses results in a change in the average voltage of a clock-out pulse at the output of the arrangement. The average voltage of the clock-out pulse is compared to a reference voltage to produce a control signal which adjusts the average voltage at the output. Critical transitions in the clock pulses occur at precise time relationships under the control of the control signal.
