A Wide-Band CMOS Low-Noise Amplifier for TV Tuner Applications

Abstract
A wide-band CMOS low-noise amplifier (LNA) is presented,in which the input MOSFET thermal noise is canceled by exploiting a noise-canceling technique.The chip was implemented in a TSMC 0.25μm 1P5M RF CMOS process.Test results show that in the range of 50~860MHz,the voltage gain is about 13.4dB,and the noise figure (NF) is below 3.5dB with a minimum NF value of 2.4dB at 350MHz.The input-referred 1dB compression point is -6.7dBm,and the IIP3 is 3.3dBm.The chip consumes 30mW with a 2.5V power supply. -
