Abstract
An apparatus comprising a plurality of serially coupled delay cells configured to generate an output signal having a frequency varied in response to a control signal. Each of the delay cells may be configured to generate one or more intermediate signals in response to the control signal and present the intermediate signals to a next of the delay cells. One or more next to the last of the intermediate signals may be fed back to a first of the delay cells. One or more last of the intermediate signals may be presented as the output signal.
