Abstract
An integrated circuit delay device includes a digital delay line configured to provide a percent-of-clock period delay to a timing signal received at an input thereof, in response to a control signal. This control signal has a value that specifies a length of the delay. A delay line control circuit is also provided. The delay line control circuit is configured to generate the control signal by counting multiple cycles of a high frequency oscillator signal (e.g., ring oscillator signal) having a period less than the clock period, over a time interval having a duration greater than the clock period.
