An SOI precision voltage reference has been developed and verified that provides a buffered, low-noise output well suited for general purpose high temperature and/or wide temperature range applications. The reference provides 0.3% accuracy from 25°C to 225°C, with rms output noise of less than 5μV at 225°C. This reference was designed for use as a reference source for high-resolution A-to-D con...

A 2.5V high precision BiCMOS bandgap reference with supply voltage range of 6V to 18V was proposed and realized. It could be applied to lots of Power Management ICs (Intergrated Circuits) due the high voltage. By introducing a preregulated current source, the PSRR (Power Supply Rejection Ratio) of 103dB at low frequency and the line regulation of 26.7μV/V was achieved under 15V supply voltage a...

The process of magnetron sputtering of dielectric zinc oxide (ZnO) films at a constant current source, was studied. It is demonstrated that this method of dielectric films deposition makes it possible to obtain high-quality coatings and layers that meet the requirements for creating multilayer diffractive optical elements.

In order to minimize the influence of electrode polarization and noise in impedance measurements, especially in the low frequency region, current injection shows several advantages compared to voltage application. Although the existence of a great variety of current sources, they meet our requirements only partially. We developed a voltage controlled current source for active front ends for a w...

How businesses resolve customer complaining behavior effectively has been considered a “defensive marketing” strategy [12] or a “zero-defections” [22] strategy, which diminishes customer dissatisfaction. Handling customer dissatisfaction accompanies Web customer complaint management, which might be the critical issue for online customer service solutions and e-CRM. In this paper, the authors 1)...

A dynamic model for current controlled induction motor drive is developed, and a time response approach for analyzing transient behavior is formulated by means of d-q variables in the synchronously rotating reference frame. A well damped closed loop response is possible if slip frequency and current magnitude control are imposed by proper tuning of control elements of PI controller.

Suppose T is an infinite resistive electrical network with resistors of the form (2). We prove an existence and uniqueness theorem for the current generated by external current sources by establishing the analogue of Thomson's principle in suitable modular sequence spaces.

We show that the effect of a high-temperature environment in current transport through a normal metal-insulator-superconductor tunnel junction can be described by an effective density of states in the superconductor. In the limit of a resistive low-Ohmic environment, this density of states reduces into the well-known Dynes form. Our theoretical result is supported by experiments in engineered e...

Active power filter are been widely used for harmonic elimination. Harmonics are generated by nonlinear load in ac distribution system. The active power filters are broadly classified as shunt active power filter, series active power filter and hybrid filters. With regard to circuit topology, there are two basic kinds of active filter, voltage source and current source. The series active power ...
