Abstract

A circuit including a logic gate responsive to a clock signal and to a control signal. The circuit also includes a master stage of a flip-flop. The circuit further includes a slave stage of the flip-flop responsive to the master stage. The circuit further includes an inverter responsive to the logic gate and configured to output a delayed version of the clock signal. An output of the logic gate and the delayed version of the clock signal are provided to the master stage and to the slave stage of the flip-flop. The master stage is responsive to the control signal to control the slave stage.
