Abstract
An adjustable delay circuit includes first and second transistors each having a control input coupled to an input node of the adjustable delay circuit and an output coupled to an output node of the adjustable delay circuit. The adjustable delay circuit includes a first pass gate coupled between first and second capacitors and the output node of the adjustable delay circuit. The first and the second capacitors are coupled between a node at a high voltage and a node at a low voltage. The first pass gate is operable to be controlled by a first delay control signal.
