A 1V, 2.4GHz fully integrated LNA using 0.18μm CMOS technology

A 1V, 2.4GHz fully integrated CMOS low noise amplifier (LNA) including the 50 Ω referenced input output matching networks is implemented using 0.18μm technology within a chip area of 4.1mm2. The amplifier has the noise figure (NF) of 3.8dB and forward gain of more than 20dB. The details of the LNA analysis and design procedure are presented in this paper.
