Abstract

This paper presents a 1V low noise amplifier (LNA) for 700~900MHz WSN applications in 0.18mm RF CMOS process.The LNA uses capacitor cross-coupled, current-reused and noise cancellation techniques to reduce noise and power consumption.The simulation results are as follows: The voltage gain is variable with high gain at 22dB and low gain at 0dB. At low gain mode, the input referenced 1dB compression point (IP1dB) is -15dBm and the input 3rd intercept point (IIP3) is 1dBm. The noise figure (NF) at high gain is 2.85dB (@800MHz).It consumes about 0.9mA current from 1V power supply.
