Abstract
A circuit for reducing duty-cycle distortion in an integrated circuit implementing dual-edge clocking is described. The circuit also comprises a plurality of circuit elements that enable the routing of data generated at outputs of the circuit elements; a plurality of register circuits that store data at outputs of the plurality of circuit elements; a clock circuit routing a clock signal to clock inputs of the plurality of register circuits; and a pulsed-controlled register circuit coupled to an output of a circuit element and generating a pulsed output coupled to a clock input of a register of the pulse-controlled register circuit; wherein the pulsed output is coupled to the clock input of the register to enable the pulse-controlled register circuit to store data at a time that is different than an edge of the clock signal. A method of reducing duty-cycle distortion in an integrated circuit implementing dual-edge clocking is also described.
