A compact reconfigurable CMOS low‐noise amplifier (LNA) is presented for applications in DCS1800, UMTS, WLAN‐b/g and Bluetooth standards. The proposed LNA features first a current reuse shunt‐feedback amplifier for wideband input matching, low‐noise figure and small area. Secondly, a cascode amplifier with a tunable active LC resonator is added for high gain and continuous tuning of bands. Fabricated in a 0.13 μm CMOS process, the measured results show >20 dB power gain, <3.5 dB noise figure in the frequency range of 1.8–2.4 GHz, return losses S 11 and S 22 lower than −12 and −14 dB, respectively, with a moderate IIP3 of −11.8 dBm at 2.4 GHz. It consumes 9.6 mW from a 1.2 V supply voltage, while occupying an active silicon area of only 0.052 mm 2 .
