Abstract: The attempt made in the paper shows an innovative designing for the enhancement and reliability in CMOS technology. A 2.4 GHz resistive feedback narrowband noise amplifier (LNA) using a series inductor input matching networks. It is easy reliable with an extra gm boosting as well as inductively degenerated topology. By using this resistive feedback topology increases the gain as well as noise figure of 2.2 dB,S21 parameter of 26dB,and IIP3 of -13dBm,while 2.8mW of power consuming from a 1.2V and its area 0.6mm2 in 0.13µm CMOS ,which gives the best figure of merit and performance.

Keywords: LNA, CMOS, noise figure, resistive feedback, gm boosting, voltage gain boosting.
