Abstract

A low-power, low 1/f noise RF receiver front-end for 900 MHz IEEE 802.15.4 ZigBee standard in 0.18 mum CMOS technology is implemented. In combination with LNA, a passive mixer showing excellent 1/f noise is adopted. The measured results show the conversion gain of 30 dB, NF of 3 dB with 1/f noise corner frequency of 30 KHz. Two-tone test measurements indicate -5 dBm IIP3, +45 dBm IIP2. The RF receiver front-end dissipates 2 mA from 1.8 V supply

具有3db NF和30khz 1/f噪声角的900mhz CMOS射频直接转换接收机前端

采用0.18 μ m CMOS技术实现了900 MHz IEEE 802.15.4 ZigBee标准的低功耗、低1/f噪声射频接收器前端。结合LNA，采用了具有良好1/f噪声的无源混频器。测量结果表明，转换增益为30 dB, NF为3 dB, 1/f噪声角频率为30 KHz。双音测试测量指示-5 dBm IIP3， +45 dBm IIP2。射频接收器前端从1.8 V电源耗散2 mA
