Low Noise Low Power Amplifiers
2013Various of noise sources in CMOS technology are introduced in this chapter, including KT/C noise, flicker noise, resistor and MOSFET’s thermal noise, etc. In order to decrease or even get rid of the noise especially the lower frequency noise, different kinds of low noise amplifiers are described. Then a design example is introduced.

Low-Noise Parametric Amplifier
Proceedings of the IRE, 1960The theory of the parametric amplifier has been reformulated to permit the prediction of noise temperature and pump power in terms of the physical parameters of the nonlinear element and circuit. The results of this analysis are supported by careful experiments at S-band using a gold-bonded germanium semiconductor diode.

Abstract The usefulness of a low-noise amplifier depends upon the noise environment in which it is used, and upon the way in which it is used. Noise received by the aerial originates in extraterrestrial sources, in the atmosphere, and from the ground.

Ostensibly, one key component of any receiver chain is the low-noise amplifier (LNA) coming off the antennas. Since the signal at that point is comparatively weak, good gain and noise performance are necessary.

In this chapter the theory and mathematics of general LNAs are explored. This is the first chapter in which practical LNA configurations are explored in detail, whereas previous chapters served as a build-up towards this chapter, describing the background of millimeter-wave research, amplifier design, semiconductor technologies and active and passive ...

Proceedings of the IRE, 1948
This paper describes an amplifier circuit which yields very low noise factor, consisting of a grounded-cathode triode followed by a grounded-grid triode. The combination is entirely noncritical and provides the low noise factor of a triode with the high amplification and stability of a pentode.

Low power reactive feedback CMOS Low Noise Amplifier
2014 International Conference on Communication and Signal Processing, 2014In this paper, the design of a wideband reactive-feedback Low Noise Amplifier based on current-reuse transconductance boosting is described. The circuit is implemented in UMC 0.13um CMOS process. The simulated noise figure (NF), input return loss (S11), output return loss (S22) and the total power consumption are less than 3dB, -10dB, -10dB and 10mW ...

Broadband Low-Noise Amplifiers
2017Although some configurations were already mentioned in Chap. 5 (mostly, feedback configurations), the techniques to turn narrowband LNAs into broadband LNAs are the topic of this chapter. The chapter opens with a discussion of some popular RF broadband topologies, their general circuit diagrams and their advantages and disadvantages.

Noise Analysis for UltraWideBand Low Noise Amplifiers
2007 Canadian Conference on Electrical and Computer Engineering, 2007Noise performance is the most important property of any low noise amplifier. Different conventional cascode ultrawideband 3.1-10.6 GHz low noise amplifier (LNA) topologies have been studied and compared in terms of noise figure (NF). The effect of an inductive inner stage on noise has been discussed. A novel two by two linear correlated matrix has been
