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 Power/Low Noise Electronics
2001Abstract : Army communication systems have several major limitations, including limited bandwidth, low throughput, dependence upon terrestrial line-of-sight, lack of full mobility and limited support for intelligence and imagery requirements. Additional requirements include low probability of intercept, jam resistant, multi-frequency systems and low ...

The author describes a set of design rules which are general and can be used to produce oscillators with a very low noise performance where both additive and flicker noise are considered. Linear theories which accurately describe the noise performance of resonator-type oscillators are presented.

Contrast enhancement and noise removal are coupled problems for low-light image enhancement. The existing Retinex based methods do not take the coupling relation into consideration, resulting in under or over-smoothing of the enhanced images.

An axial flow fan includes blades mounted on a hub and extending radially outward to a shroud disposed around the hub. Pairs of stators are connected to the shroud at positions angularly spaced about the inner periphery of the shroud. Each pair of stators includes a trailing stator angularly spaced from a leading stator by a distance related to the ...

Much of the recent progress in our understanding of the world around us was achieved through the ability to detect very weak signals, for example from outer space, from nerve fibers, or from the ocean floor. To detect these weak signals, one requires very sensitive receivers, and hence the ability to amplify these signals without, at the same time ...
