NOVEL DESIGN PARAMETERS FOR CMOS LOW NOISE AMPLIFIER

This paper presents the study of different important parameters which are considered for LNA design. Input/output matching, noise figure, Stability, Bandwidth, Gain, Power dissipation and Linearity are the key factors of any receiver. First and main part of receiver is LNA whose gain should be greater than 15 dB, Noise figure less than 2dB and power dissipation in mw to achieve the desired specification. A number of topologies are available to achieve proper matching and high gain. Different topologies are used to adjust the tradeoff among design parameters like Bandwidth, Linearity NF, Gain, Power dissipation, Impedance matching.
