چکیده
this paper surveys recent research on Low Noise Amplifier (LNA) design for Cognitive Radios (CR). Design challenges and requirements of CR are discussed and recent advances in topologies and design techniques are presented, compared and summarized. The classical trade-offs of linearity, gain, input impedance matching and noise are discussed herein with respect to the Wide Bandwidth requirement. Keywords— LNA Design, Low Noise Amplifier, Wideband, RF, Cognitive Radio.

Analysis and Design of Cmos Wide-band Low Noise Amplifiers
The implementation of Low Noise Amplifier (LNA) front-ends is one of the challenging aspects in emerging Ultra Wide-Band (UWB) radio frequency (RF) systems. As it is highly desirable to achieve complete system-on-chip (SoC) integration, several CMOS based LNA implementations have been reported recently. The first part of this thesis presents a comparative study that helps designers understand t...
متن کاملA New Ultra-Wideband Low Noise Amplifier With Continuous Gain Control
This paper presents a new variable gain low noise amplifier (VG-LNA) for ultra-wideband (UWB) applications. The proposed VG-LNA uses a common-source (CS) with a shunt-shunt active feedback as an input stage to realize input matching and partial noise cancelling. An output stage consists of a gain-boosted CS cascode and a gain control circuit that moves the high resonant frequency to higher freq...
