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. |
