    I posted it on the forum. Its just an XOR gate with a single pole RC filter on one of the inputs. There is a pulse for each edge of the original signal and the value of R an C controls the pulse width based on the threshold of the gate in question. CMOS gates normally have their threshold set at Vdd over 2

    Is the signal you are trying to double a squarewave or is it sinewave?
