Abstract

See full text

A delay line circuit includes: a coarse-tuning arrangement, including delay units; and a fine-tuning arrangement including at least three serially-connected inverters. The coarse-tuning arrangement is configured to receive an input signal and coarsely-tune the input signal, the coarsely-tuning including transferring the input signal through a selected number of the delay units and thereby producing a first output signal. The fine-tuning arrangement is configured to receive the first output signal, finely-tune the first output signal, and produce a second output signal, the finely-tuning including selectively connecting a speed control unit to a node between a corresponding pair of the at least three serially-connected inverters.
