ABSTRACT:
A programmable delay element with a variable delay generator employs feed forward and feedback control signals to corresponding feed forward and feedback control elements integrated within the variable delay generator. The variable delay generator is responsive to a control signal. The variable delay generator uses transfer switches to couple reactive circuit elements to a signal node in accordance with the control signal. The feed forward element couples a fixed voltage to corresponding nodes of the feed back element. The feedback element completes a bypass circuit to apply the fixed voltage to the signal node once the programmable delay element has delayed a source signal. The feed forward element is responsive to a buffered version of the source signal. The feedback element is responsive to a buffered version of the output of the delay element. A corresponding method for reducing frequency induced delay variation in a programmable delay element is disclosed.
