A Wideband Variable Gain Differential CMOS LNA for Multi-standard Wireless LAN

摘要：

This paper describes a wideband variable gain LNA for multi-standard wireless LAN operatingInthe frequency bands of 4.9～5.825 GHz,including three standards: IEEE 802.11a,ETSI HiperLAN2 and MMAC HiSWANa. By using a simple feedback loop at the second stage of LNAWe realized the continuous gain control.A variable gain range of 18.7 dB (0.7 dB to 19.4 dB) is achieved. The noise figure is 1.1 dB at the maximum gain and the input 1-dB compression point is -3.5 dBm at the minimum gain,while the DC power consumption is 12.6 mW underA 1.8V supply voltage.
