摘要
提出了一种新型基于相位选择结构的三模预分频器,与传统结构相比,提供了更多可选的分频比和更宽的输出频率覆盖范围,同时不增加电路复杂度与功耗,可以应用于支持多种无线标准的超高频频率合成器。设计采用了TSMC 0.18μm Analog/RF CMOS工艺,电源电压2.0V。仿真结果表明,电路最高工作频率为7.5GHz,最大电流消耗小于3.4mA。
A triple-modulus prescaler based on novel phase-switching is proposed in this paper. It provides more division ratio and wider frequencies cover range without the additional complexity and power, can be applied to ultra-high frequency synthesizers for different wireless standards. The prescaler is fabricated in TSMC 0.18um Analog/RF CMOS process. The simulation shows it demonstrates a maximum operating frequency of 7.5GHz with less than 3.4mA current in 2V supply voltage.
