An integrated circuit includes a first time delay circuit, a second time delay circuit, and a master-slave flip-flop having a gated input circuit and a transmission gate. The transmission gate is configured to receive the first clock signal and the second clock signal to control a transmission state of the transmission gate. The gated input circuit is configured to have an input transmission state controlled by the third clock signal at the second output of the second time delay circuit. The second time delay circuit further includes a second gate-conductor and a second gate via-connector in direct contact with the second gate-conductor. The second gate-conductor intersects a first-type active region structure and a second-type active region structure in a second area, and wherein at least a portion of the second gate via-connector is atop the second-type active region structure.
