Design and Implementation of a Dual-Band Concurrent Fully-Integrated LNA for W-LAN IEEE 802.11b/g/a Applications
Résumé
This paper presents a dual-band concurrent fully-integrated low noise amplifier (LNA) targeted to WLAN IEEE 802.11b/g/a standards. The use of a concurrent topology enables saving die area and power consumption compared to the parallel solution that employs two separated LNAs. An original design methodology that helps in the selection of input/output matching network element values is also presented. The LNA die area is 1.0 x 0.9 mm² and it consumes 9mW (5mA at 1.8V)
