Abstract

Disclosed is a method and apparatus for variably and independently delaying the rising and falling edges of a digital waveform including a dual polarity output buffer, a first delay circuit, a second delay circuit and a recombination circuit. The dual polarity output buffer outputs a first signal that is a substantial replica of the input signal and a second signal that is an inversion of the input signal. The first delay circuit is connected to the dual polarity output buffer and generates a first time delay in the rising edges of the first, non-inverted signal. The second delay circuit is also connected to the dual polarity output buffer and generates a second time delay in the rising edges of the second, inverted signal. The recombination circuit is connected to both the first delay circuit and the second delay circuit and combines the outputs thereof to generate a composite output signal representing the input signal with both the rising edges thereof and the falling edges thereof delayed independently.
