Glitch less delay circuit for real-time delay adjustments
An apparatus is disclosed in which a clock signal may propagate through a delay circuit. The delay circuit may include a first and a second delay stage, in which each delay stage may be programmable for one of two delay times, depending on a value of a respective control signal to each delay stage. The delay circuit may also include circuitry which may change the value of the respective control signal from a first value to a second value. The circuitry may change the value of the respective control signal responsive to a determination that an output of the first stage and an output of the second stage are equal.
