An elegant CMOS LNA design using feed-forward noise and distortion cancellation technique is presented in this paper. The design is implemented in 130nm CMOS technology. In comparison to other conventional technique the proposed LNA shows improvement in performance parameter such as NF, gain, stability and power dissipation. . In this paper a CMOS inverter along with resistive negative feedback is used to provide necessary biasing and impedance matching at input port. The LNA design is inductorless and hence the size is small. Using this technique LNA shows a gain of 34-22 dB with a noise figure of 1.6-1.9dB for operating bandwidth of 600 MHz – 3GHz. The proposed LNA drains 13mA current from 1.2V power supply.
Author Keywords: LNA, noise cancelling, low power, high gain, inductorless.

Abstract
An elegant CMOS LNA design using feed-forward noise and distortion cancellation technique is presented in this paper. The design is implemented in 130nm CMOS technology. In comparison to other conventional technique the proposed LNA shows improvement in performance parameter such as NF, gain, stability and power dissipation. . In this paper a CMOS inverter along with resistive negative feedback is used to provide necessary biasing and impedance matching at input port. The LNA design is inductorless and hence the size is small. Using this technique LNA shows a gain of 34-22 dB with a noise figure of 1.6-1.9dB for operating bandwidth of 600 MHz – 3GHz. The proposed LNA drains 13mA current from 1.2V power supply.
Author Keywords: LNA, noise cancelling, low power, high gain, inductorless.
