Abstract: A pulse circuit contains an input stage configured to receive input pulses on input nodes using push-pull elements, wherein a given push-pull element is configured to receive an input pulse on a given input node and to provide a corresponding internal signal. The pulse circuit further contains a feedback loop that includes a logic element coupled between outputs from the push-pull elements and reset nodes of the push-pull elements. This logic element is configured to provide one or more outputs from the pulse circuit and to reset the internal signals from the push-pull elements via the feedback loop.

Abstract: One embodiment of the present invention provides a domino logic circuit that operates asynchronously. This domino logic circuit contains a pipeline comprised of a number of stages of domino logic, including a present stage that receives one or more inputs from a prior stage and that generates one or more outputs for a next stage. The present stage includes a control circuit that is configured to ensure that the present stage enters a precharging state before entering an evaluation state—in which one or more inputs of the present stage are used to generate one or more outputs. This control circuit operates by receiving a prior control signal from the prior stage and sending a present control signal to the next stage. During this process, the control circuit ensures that a minimum cycle time between successive evaluation states is six gate delays.
