Abstract

A 2.4 GHz high linearity and low noise down-conversion mixer is designed in SMIC 0.18-μm RF CMOS technology, which will be used in applications such as IEEE 802.11b/g WLAN, Wi-Fi Systems, ISM Band Systems, etc. The proposed mixer adopted Source inductor degeneration and current-reuse bleeding technique. The simulation results show that under a single 1.8 V supply voltage, the mixer achieves: -0.34 dBm input 1 dB compress point; 10.3 dB noise figure; -0.78 dB conversion gain with 8 mW power dissipation. The layout size is 850×500 μm².
