    Abstract

    This paper presents a low power multiband multimode low noise amplifier (LNA) targeting for GSM/LTE, WiMAX and IEEE 802.11 family standards. Wireless bands are reconfigurable by using selection of parallel cascode amplifiers and buffers with switching input inductors. Inductively degenerated cascode amplifiers, sharing the same transconductance for different bands, achieve good input matching and NF. Gain control is designed to provide equal gain for each band and for multimode operation. The maximum power gain is from 13 to 17 dB over different bands with controlled range of over 15dB. The NF is 1.6/2.8/2.7/3.1 dB at 1.9/2.4/3.5/5.2 GHz bands, respectively. The LNA achieves an average IIP3 of -17.5 dBm while consumes from 3 to 5.3 mW for different bands. The proposed reconfigurable LNA is designed in 0.18-μm CMOS process from 1.5V supply.
