Abstract
A deglitch circuit for suppressing transient signals that appear at an output node includes a bias circuit for providing a bias signal; a transistor having its collector-emitter conduction path coupled in series to the output node and having a base coupled to the bias signal; and a capacitive element coupled between the output node and the base of the transistor for rendering the transistor conductive in response to a transient signal such that a low impedance circuit path is presented to the transient signal.
