摘要
采用90nm CMOS工艺,实现了一个基于电流模式逻辑的12GHz二分频器。该分频器具有很宽的锁定频率范围(1~12GHz),在输入信号频率为8GHz时,输入灵敏度达到-30dBm。分频器工作在1.2V电源电压下,消耗的电流大约为1.5mA。给出了该设计的后仿真结果。
A 12 GHz divided-by-2 frequency divider based on current mode logic (CML)was implemented using 90 nm CMOS process technology. The divider showed a wide frequency locking range from 1 GHz to 12 GHz, and it had an input sensitivity as high as -30 dBm at 8 GHz. The device drew around 1.5 mA of current from a 1. 2 V supply. Post simulation has been done for this design.
