Design And Implementation Of A Dual-band Concurrent Fully-integrated Lna For Wlan Ieee 802.11a/b/g Applications

摘要

This article presents a dual-band concurrent fully-integrated low-noise amplifier (LNA) targeted to WLAN IEEE 802.11a/b/g standards. The use of a concurrent topology enables saving die area and power consumption compared with 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 × 0.9 mm~2 and it consumes 9 mW (5 mA at 1.8 V).
