Abstract :
In this paper, we present some design problems of the high speed master-slave D-type flip-flop (MS D-FF). Essential to long haul optical fiber communication systems, this circuit is critical since it operates at the highest clock frequency for a given bit rate. We discuss specific aspects of electrical design of such a circuit and underline some important points of the layout of gigabit circuits. The MS D-FF was fabricated in our self-aligned InP DHBT technology. On wafer measurements show correct operation at 40 Gb/s.
