Abstract
In this paper, we proposed low noise amplifier for 2.4GHz ISM frequency with CMOS technology. The property of noise and gain is improved by cascode architecture. The architecture, which common source output of cascode is connected to input of parallel MOS, reduce IM. The LNA results based on Hynix 0.35${\mu}{\textrm}{m}$ 2poly 4metal CMOS processor with a 3.3V supply. It achieves a gain of 13dB, noise figure of 1.7dB, IP3 of 8dBm, Input/output matching of -31dB/-28dB, reverse isolation of -25dB. and power dissipation of 4.7mW with HSPICE simulation. The size of layout is smaller than 2 ${\times}$ 2mm with Mentor.
