Abstract
A method of providing a clock signal for an embodiment includes performing a calibration for a closed loop control system to determine a control signal value that provides a desired tuning of the closed loop control system. The control signal value is stored and provided to a delay circuit, wherein a delay range and a delay step size of the delay circuit is based on the control signal value. A delay select control signal is provided to the delay circuit to select a specific delay within the delay range.
