Abstract
A delay-line circuit that includes both fixed-delay line circuit and a variable delay-line circuit is disclosed. The fixed delay-line circuit may generate a first output clock signal by delaying an input clock signal by a particular delay period. The variable delay-line circuit may include multiple fixed-delay circuits and variable-delay circuits, and may select a particular subset of the fixed-delay circuits and the variable delay circuits based on a frequency of the input clock signal. The particular subset of the fixed-delay and variable-delay circuits may generate a second output clock signal by delaying the input clock signal by another delay period different than the particular delay period.
