Abstract
A delay circuit includes an output voltage controllable BICMOS delay element that is coupled to a phase locked loop that develops a control voltage. The control voltage is applied to the output BICMOS delay element and to another BICMOS delay element in the phase locked loop. An input voltage is applied to the phase locked loop and, along with the output of the phase locked loop, to the output BICMOS delay element.
