Abstract
An apparatus precisely adjusts the delay of a clock signal so as to reduce clock skew. The electronically programmable skew adjustment can be self-contained within a single IC package. The apparatus has an input for receiving a signal to be delay adjusted, delay elements including capacitive delay elements for providing multiple signal paths of various delays, delay selection circuitry for selecting the signal paths so as to select a delay amount, and an output to provide the delay adjusted signal to a load.
