Research on low voltage high speed 1:2 frequency divider based on 0.13μm CMOS

In optical fiber transmission system, is working at the highest frequency divider circuit, one plays a vital role, this paper uses the figures from the latch constitute a 1：2 divider. This paper describes a 1：2 frequency divider, which works on the power supply voltage of 1V and the frequency range of 5GHz to 20GHz, using UMC 0.13μm CMOS process. The concrete circuits are composed of frequency divider and I/O buffers. A singe-end dynamic loading latch is employed as basic cell. The total power consumption of the chip is lower than 17mW, and core power consumption is 2mW ,and die area equals 0.412mm×0.337mm. Through the system test shows that the design can meet the design requirements.
