Abstract
In certain aspects, a digital circuit comprises a delay line to generate a plurality of delayed versions of an input clock. The digital circuit also comprises selection circuitry to provide a selected one of the plurality of delayed versions of the input clock based on a clock selection signal and feedback circuitry to generate the clock selection signal based on the selected one of the plurality of delayed versions of the input clock and based on the input clock. The clock selection signal is further used for selecting and generating other clocks and/or for variation control.
