a high accurate and low-voltage analog cmos current divider which operates with a single power supply voltage is designed in 0.18µm cmos standard technology. the proposed divider uses a differential amplifier and transistor in triode region in order to perform the division. the proposed divider is modeled with neural network while tlbo algorithm is used to optimize it. the proposed optimization...

consideration of the current-voltage (i-v) characteristics variations of solar modules with temperature and irradiations variations is basic for maximum power point tracking (mppt). having a simple and accurate mathematical model for the optimize utilization of the solar modules is essential. in this paper, a novel modeling of photovoltaic systems with novel coefficients is proposed for mathema...

A 32 by 32 array of packaged 100 μm Geiger-mode avalanche photodiodes were tested and characterized. A breakdown voltage of 32 V was measured; at or just above this voltage is where the device should be biased in order to operate in Geiger-mode. The ideal region of the forward biased IV curve resulted in an ideality factor of 1.0 and no recombination/generation region. In addition, IDL code was...

Electronic quantum transport acounting for coherent propagation and electronphonon (e-p) scattering has been used to calculate the current-voltage characteristic for model nanostructures.

The performance data of a PV module are derived from the current-voltage characteristic measured under standard test conditions (STC). For this purpose, test laboratories as well as module production plants employ solar simulators which, depending on type and module size, display a more or less pronounced non-uniform distribution of irradiance in the test plane. In view of the quality assurance...

The potential drop across a bipolar membrane was measured as a function of the applied current density. As a result, an inflection point was observed in the obtained current-voltage curve at high current density. This inflection point indicates that at high current densities water supply from outside of the bipolar membrane to the interface between a cation and an anion exchange layer is the ra...

This paper presents ageing experiments controlled by the evolution of junction parameters. The deterioration of the device is related to high injection effects which modified the transport mechanisms in the space charge region of the junction. Physical phenomena linked to the degradation of junction parameters that affect the devices reliability are reported and discussed. We have used the meth...

We demonstrate how to configure and reconfigure a nanoelectronic nonlinear network to a universal set of logic gates by applying sequences of voltage pulses to the edges of the network. The nanoelectronic device is designed to consist of a self-assembled network of nanoparticles connected by two-terminal linker elements with hysteretic behaviour, allowing voltage-controlled switching between a ...

We present a general analysis of instabilities and oscillations of the sequential tunneling current in superlattices, based on the current-voltage characteristic of a single barrier. Our results depend only on the presence of a negative differential resistance region and are independent of the details of the model. We establish general conditions for the existence of a stable oscillatory region...
