Abstract
A logic transition detection circuit for detecting logic signal changes. The circuit includes both positive and negative transition detectors for providing a charge at the input of an output stage of the detection circuit when the logic signal changes. A reset circuit is coupled between the output stage and the respective transition detectors for discharging the input of the output stage of the detector, thereby resetting the detector circuit. The output stage resulting provides a pulse denoting that a transition in the logic signal has occurred.
