Abstract :
In this paper, a low supply static 2:1 frequency divider based on 0.13 mum CMOS is presented. It is designed for 40-Gb/s optical communication systems. Current-mode logic (CML) is adopted because of the higher speed compared to static CMOS and the robustness against common-mode disturbances. This frequency divider is designed with output buffer to drive the external 50 Omega loads. On-chip shunt peaking (SP) inductors and split-resistor (SR) loads are used to boost the bandwidth. The frequency divider uses a single 1.2-V supply voltage and consumes a total current of 32 mA. And the chip area is only 0.63 mm2 with bonding pads.
