A precision wide-range variable delay system whose delay is independent of process, voltage, and temperature variations. A delay controller supplies a voltage, that is independent of process, voltage, and temperature variations, and that is used in a delay line to set the amount of delay through all...http://www.google.fr/patents/US6268753?utm_source=gb-gplus-shareBrevet US6268753 - Delay element that has a variable wide-range delay capability
