摘要
本文基于目前流行的TSPC高速电路,利用状态机原理提出了一种可实现任意分频比的射频双模预分频器电路;并且提供了分频比为10/11的具体实现电路。在这个除以10/11分频器当中,基本的D触发器单元采用了目前流行的高速TSPC与E-TSPC结构,同时具备低功耗和高输入频率的特点。电路采用SMIC0.18μ mRFCMOS工艺,利用Cadence Spectre仿真显示,采用1.8V电源电压供电,环境温度为27℃时,最高的工作频率可达到6GHz,此时整个分频器消耗的电流仅为831μA。
In this paper, a high speed prescaler with an arbitrary divide ratio is proposed. As an example,a divide-by-10/ 11 prescalar is implemented. Ali the D flip-flops in this presealar are constructed in TSPC technology, which can provide both lower consumption and a high speed. This prescalar implemented using the SMIC 0. 18 μm RFCMOS process is capable of operating up to 6 GHz for a 1.8 V supply voltage at 27℃ with a current as low as 831 μA.
