Abstract
A new dual-band, 2.4 and 5.2 GHz, combined LNA, which can operate at 1 V supply only, for WLAN application is presented. The switched transistor technique is used in the LNA. It could match the input port in two frequency bands and reduce one on-chip spiral inductor usage compared with [1, 2]. Theoretical analysis and transistor level simulation results using 0.18 ?m CMOS process from Chartered Semiconductor are presented to demonstrate this idea.
