This paper presents a reconfigurable inductor-less CMOS low noise amplifier (LNA) for multi-standard wireless applications. The LNA is designed to address PCS1900, UMTS, WLANb/g and Bluetooth frequency bands. The LNA is based on two cascaded stages. The first stage is a resistive feedback amplifier which achieves a wideband matching in order to address the different application frequency bands while performing a low noise figure. The second stage is a cascode amplifier with an active output LC resonator in order to select the desired bandwidth while achieving high gain and low surface area. The proposed multi-standard LNA, implemented in a 0.13μm CMOS technology achieves more than 26dB gain from 1.8 to 2.4GHz for a noise figure less than 3.4dB. The input and output return losses S11 and S22 are lower than -12dB and -16dB respectively. The LNA consumes 9.6 mA from 1.2V supply voltage and occupies a chip area of 0.165mm2 including pads.
