Dynamic logic circuit

摘要

A dynamic logic circuit having a charging circuit, comprising a first transistor having a first source/drain electrode adapted for coupling to a voltage supply and a second source/drain electrode connected to a node. The charging circuit couples the voltage supply to the node to place an initial charge on the node. A data transfer circuit is provided comprising a second transistor having a gate adapted for coupling to an input strobe pulse, a first source/drain electrode connected to the node, and a second source/drain electrode responsive to an input data and the input strobe pulse, for transferring the input data to the node to the node such that the pre-charged node is either discharged or remains depending on the input data. An output circuit is responsive to an output strobe pulse for coupling the data at the node to an output. A trailing edge detector of the output strobe pulse detects a time at which the coupling of the data to the output is complete and pre-charges the node at a high level for a subsequent input strobe pulse. <IMAGE>
