In this paper, a differential multi-band CMOS low noise amplifier (LNA) is proposed that is operated within a range of 1500–2700 MHz with input matching capacitor switching and gain flatness performance enhancement technique. Traditional multi-band LNAs have poor performances on gain flatness performance. Therefore, we propose a new multi-band LNA which obtain good gain flatness performance by integrating the characteristics of the transistor trans-conductance and LC resonant load. The new LNA can also achieve a tunable frequency at different matching capacitance conditions. The post-layout simulation results shows that the voltage gain is between 19.3 dB and 22.4 dB, the NF is less than 2.5 dB, and the 1-dB compression point is about -5.1 dBm. The LNA consumes 17.79 mW under 1.8 V supply voltage in TSMC 0.18-um RF CMOS process.

With rapid expansions of wireless communications, requirements for transceivers that support concurrent multiple services are continuously increasing and demanding design of a concurrent low-noise amplifier (LNA) with low noise figure (NF), high gain, and high linearity over a wide frequency range for various wireless applications. The proposed work focuses on a concurrent multi-band LNA that works at navigational frequencies, namely, of 1.2[Formula: see text]GHz and 1.5[Formula: see text]GHz, wireless communication frequencies, namely, of 2.45[Formula: see text]GHz and 3.3[Formula: see text]GHz, dedicated short range communication (DSRC) frequency of 5.8[Formula: see text]GHz for the vehicular communication applications. This circuit has a distinct input matching network which resonates at all desired five frequency bands and is achieved by adapting frequency transformation method. To accomplish simultaneous reception of the desired penta-band, the output matching is designed with simple LC matching network with the aid of load-pull methodology.
