A Low-Noise, Low-Power Amplifier With Current-Reused OTA for ECG Recordings
IEEE Transactions on Biomedical Circuits and Systems, 2018This paper presents a low-power and low-noise capacitive-feedback amplifier with a current-reused OTA for ECG recordings. To improve the noise-power efficiency, the proposed OTA employs a current-reused architecture, which adopts an inverter-based ...

The Journal of the Acoustical Society of America, 1985
A practical method of computation is described for making periodic signals V(t) which have a given frequency spectrum and which minimize the variance 〈(V2−〈V〉2)2〉 in power as a function of time. These signals can be used to measure the spectral response of a system (the transfer function): They represent a significant improvement over traditional ...

A Wideband 2–5 GHz Noise Canceling Subthreshold Low Noise Amplifier
IEEE Transactions on Circuits and Systems - II - Express Briefs, 2018This brief presents an energy efficient wideband low noise amplifier (LNA) operating in subthreshold regime. Wideband matching and low noise figure in subthreshold domain is achieved by using a gate inductor-assisted impedance matching and a current ...

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 ...

1992 IEEE Microwave Symposium Digest MTT-S, 2003
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.
