Abstract
A counter-controlled delay line includes a main oscillator for delaying edges of an input signal to generate a main clock signal. The main oscillator includes a plurality of gated delay elements connected in a ring. Each gated delay element includes a first control terminal to receive a corresponding load signal, and includes a second control terminal to receive a release signal. The release signal may simultaneously enable and disable state transitions in all delay elements, and the load signals may simultaneously drive an output of each delay element to any selected logic state.
