Abstract :
This paper presents a dual-band concurrent fully-integrated low noise amplifier (LNA) targeted to W-LAN IEEE 802.11b/g/a standards. The use of a concurrent topology enables saving important die area and power consumption compared to the parallel solution that employs two separated LNAs. An original design methodology that helps selecting input/output matching network element values is also presented. The LNA die area is 1.0 times 0.9 mm2 and it consumes 9mW (5mA under 1.8V)
