HIGH FIDELITY LOW-NOISE AND LOW-POWER AMPLIFIERS (HIFI-LNLPA) FOR DIFFERENT RECEIVERS: A REVIEW

Abstract

Low Noise Amplifiers (LNA)are the basic building blocks of different communication systems, instrumentation and computation systems.To sense the weak signal with high fidelity, low noise amplifiers plays vital role. Low noise amplifiers have variety range of applications in different receivers. For LNA design,Noise Figure, Gain, Bandwidth, Proper Biasing Conditions, Selection of Transistor, Third Order Intercept Point, Good Sensitivity, Good Linearity and Good Dynamic Range are considered. In this paper, we present different low-noise, low-power amplifier circuit’stopology and corresponding parameters comparison review for different receiver applicationsin different fields with low noise, low power, excellent gain and linearity
