Abstract
A slew rate control circuit generates a slew-rate controlled clock signal from an input clock signal based on a feedback control mechanism. The feedback control mechanism uses the input clock signal duty cycle characteristics as a reference for controlling and maintaining an optimum slew rate for the slew-rate controlled clock signal. By using the input clock signal as a reference, the slew-rate controlled clock signal is dynamically measured and periodically adjusted over each cycle of the input clock signal.
