摘要 基于D触发器的电路结构 ,采用TSMC 0 .2 5 μmCMOS工艺 ,成功地实现了12GHz 1:2动态分频器。经测试 ,该分频器在输入信号频率为 10 .5 3GHz时 ,最小可分频幅度小于 2mV ,输入信号单端幅度小于 30 0mV时 ,可分频范围为 7GHz~ 12GHz。电源电压 3.3V ,核心功耗 2 4mW。 A 12GHz 1:2 dynamic frequency divider has been realized in a standard 0.25μm CMOS technology. The circuit is based on D flip-flop and wideband output buffer. The measured results show that the core circuit consumes 24mW with 3.3V supply and the operating frequency is 7GHz to 12GHz under input signal amplitude of <300mV. Especially at 10.53GHz, the divider can work with 2mV input signal.
