Abnormal increase of low frequency flicker noise in analog nMOSFETs with gate oxide in valence band tunneling domain is investigated. In 15Å oxide devices, valence-band electron tunneling from Si substrate to poly-gate occurs at a positive gate voltage and results in the splitting of electron and hole quasi Fermi-levels in the channel. The excess low frequency noise is attributed to electron an...

In order to identify the effects of vitamin A and aspirin on reducing UV lightinduced retinopathy, ERG waves were compared before and after UV light exposure in rabbits. 30 rabbits were divided into 3 groups: the first group received vitamin A, 50,000 units I.M., single dose, the second group received aspirin, 50 mg/ kg/day PO and the third group did not receive any medication. All three gr...

Abstract: This paper presents a dual neural network based technique for detecting and classifying the power quality disturbances. In the proposed method, Adaptive Linear Neural Network is used to extract the rms voltage for harmonics and Interharmonics estimations. With the help of these indices, PQ disturbances such as Sag, Swell, Outages are detected and classified, Harmonics and Interharmoni...

This paper represents a three-phase precision measurement system for the electronic electricity meter based on a digital signal processor (DSP) in combination with a multichannel analog-to-digital converter. The measurement system capabilities include all the usual assessments of the energy, power, voltage and current, but functionality of this precision measurement system is extended into the ...

This paper proposes a flexible D-STATCOM (Distribution Static Compensator) and its new controller system, that be able to mitigate all types of faults (LG, DLG, LL, LLL and LLLG), and improve the distribution system performance. This paper validates the performance of D-STATCOM system to mitigate the power quality problems such as voltage flickers, voltage sags/swells harmonics and improve the ...

Previous experimental and computational work (for review, see White et al., 2000) has suggested that channel noise, generated by the stochastic flicker of voltage-gated ion channels, can be a major contributor to electrical membrane noise in neurons. In spiny stellate neurons of the entorhinal cortex, we remove the primary source of channel noise by pharmacologically blocking the native persist...

We present the characterization of commercial tunnel diode low-level microwave power detectors at room and cryogenic temperatures. The sensitivity as well as the output voltage noise of the tunnel diodes is measured as functions of the applied microwave power. We highlight strong variations of the diode characteristics when the applied microwave power is higher than a few microwatts. For a diod...

We investigate gate voltage dependence of electrical readout noise in high-speed rf reflectometry using gallium arsenide quantum dots. The fast Fourier transform spectrum from the real time measurement reflects build-in device and circuit including resonator amplifier. separate their spectral components by model analysis. Detail flicker is investigated compared to charge sensor sensitivity. poi...
