Abstract:
In some embodiments, a flip-flop is disposed as an integrated circuit layout on a flip-flop region of a semiconductor substrate. The flip-flop includes a first clock inverter circuit that resides within the flip-flop region, and a second clock inverter circuit residing within the flip-flop region. The first clock inverter circuit and the second clock inverter circuit are disposed on a first line. Master switch circuitry is made up of a first plurality of devices which are circumscribed by a master switch perimeter that resides within the flip-flop region of the integrated circuit layout. The master switch circuitry and the first clock inverter circuit are disposed on a second line perpendicular to the first line. Slave switch circuitry is operably coupled to an output of the master switch circuitry. The slave switch circuitry is made up of a third plurality of devices that are circumscribed by a slave switch perimeter. The slave switch circuitry and the second clock inverter circuit are disposed on a third line that is in parallel with and spaced apart from the second line.
