ABSTRACT:
Circuits, methods, and apparatus for delaying signals in a power and area efficient manner are provided. A gating element within a stage of a programmable delay element suppresses an operation of other stages of the delay element. A programmable delay has components with differing delays that may be combined to give flexibility in choices for delay increments while minimizing the area of the delay element. A delay element is shared between different signal paths, for example, to reduce the number of delay elements or to allow utilizing unused delay elements of other signal paths.
