Abstract
The paper presents a dual-band switchable low noise amplifier implemented in 0.25-μm CMOS technology for 5-GHz wireless local area network (WLAN) applications. Equipped with a PMOS capacitor together with the inductive load, the LNA is able to operate at the lower or the upper band at 5-GHz by 1-bit control signal. The LNA exhibits over 17 dB power gain, 3.5 dB noise figure and input 1-dB compression point -23 dBm in both frequency bands. The LNA draws 9.5 mA from 2.5 V supply.
