Abstract
A clock stretcher includes a digital DLL that derives delayed versions of an input clock signal, and a combiner that cyclically selects the delayed versions to generate a modified clock signal. The combiner uses a hop code, dependent on a sensed condition, to determine the step size for the cyclical selection. The digital DLL corrects its delay speed at discrete times, during which it may be active. If the DLL delay line becomes slower while it is active, the modified clock signal would incur a glitch. The clock stretcher corrects for this glitch by using an increased hop code when a speed change occurs. The clock stretcher may operate from a sensed power supply without intervening voltage regulation.
