A 2.4 to 5.4 GHz Low Power CMOS Reconfigurable LNA for Multistandard Wireless Receiver

A CMOS reconfigurable LNA is reported. By combination of switched inductors and varactors it performs continuous frequency tuning from 2.4 to 5.4 GHz with 500 MHz 3 dB-bandwidth. Switching transistor is used to provide variable gain control over a 12 dB-range. The LNA supports standards including Bluetooth, WiMAX, UWB mode-1, 802.11 b/g and part of 802.11a. Fabricated in 0.13 um CMOS process the LNA achieves up to 25 dB power gain, 2.2 dB noise figure, -1 dBm IIP3 while consuming less than 5 mW from 1-V power supply.
