摘要：
In this paper, a broadband CMOS differential LNA for 50-860MHz multi-standard terrestrial and cable TV tuner is proposed, in which the channel thermal noise and the flicker noise of input MOSFET is canceled by exploiting a noise-canceling technique. A lower noise figure and an excellent wide-band input matching can be achieved at the same time. The proposed LNA is designed with TSMC 0.18 mu m RF CMOS process. Post-simulation results show that in 50-860MHz, the gain is between 13.3-15.1 dB, the NIT is 1.7-2.2 dB, the HP3 is -0.5 dBm. It consumes 26.5 mW under a 1.8V supply. The core area is 0.53x0.23 mm(2).
