چکیده
In this paper, a differential multi-band CMOS low noise amplifier (LNA), operated in a wide range from 800MHz~1700MHz, with wide-band interference rejection, linearity improvement and the capacitive cross-coupling technology, is proposed. The proposed differential multi-band CMOS low noise amplifier with high linearity performance and good interference rejection performance. The post-simulation results of proposed LNA show that the gain is 13~17.5 dB, the noise figure (NF) is less than 3.4dB, the thirdorder intercept point (IIP3) is 9.98dBm. The LNA consumes 8.96mW under 1.8V supply voltage in TSMC 0.18-um RF CMOS process.
