A Novel Ultra High-Speed Flip-Flop-Based Frequency Divider

摘要

Frequency dividers play an important role in highspeed communications systems. In particular, optical communication circuits demand frequency dividers capable of operating well above 10 GHz, This paper presents a high-speed flip-flop-based frequency divider incorporating a new high-speed latch topology, which provides satisfactory performance for frequencies up to 17 GHz. This circuit is designed and simulated in a standard 0.18μm CMOS process.
