ABSTRACT:
In accordance with this invention there is provided a circuit for delaying a selected edge of an input signal for use in a deep sub-micron process semiconductor device, the circuit comprising an inverter element having an input and output node, a load element comprising resistive and capacitive (RC) elements a first transistor element, coupled to the RC load element and selectively operable to couple the RC element to the output node upon receipt of the selected edge of the input signal and for decoupling the RC element from the output node upon receipt of an opposite edge of the input signal, whereby a delay is introduced by the load element on the selected edge of the input signal with little negative effect on the opposite edge of the input signal.
