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
