Abstract: A glitch absorbing buffer reduces glitch power in digital circuits. The glitch absorbing buffer includes a logic element configured to identify a digital logic glitch and a delay circuit configured to selectively delay one input to a logic element. The amount of delay imposed is equivalent to a pulse width of the glitch. A Schmitt trigger may amplify the low pass behavior on the input.
