摘　　要：介绍了一种可以应用在无线传感网射频芯片中的超高速、低功耗32/33双模前置分频器的内部结构、电路设计原理以及版图设计。该前置分频器采用0.18μm RF CMOS工艺制作,工作频率范围为1~6 GHz,工作温度范围为-20^+80℃,在1.8 V电压下正常工作频率为4.8 GHz,最高工作频率达到6 GHz,电源电流为2.5 mA,满足系统指标要求。A high-speed, low-power 32/33 dual-modulus prescaler which can be used in WSN RF chips is introduced. The prescaler is produced by 0. 18μm RF CMOS technology. The prescaler＇ s operating frequency range is 1-6 GHz, and its temperature range --20-＋80℃. With the voltage of 1. 8 V, the prescaler＇s operating frequency is 4. 8 GHz, the prescaler＇s maximum operating frequency is up to 6 GHz, and its power supply current is 2. 5 mA.
