The current-voltage characteristics of Au/n-Si Schottky barrier diodes were measured in a wide temperature range of 70-310 K. The forward current-voltage characteristics have been analyzed on the basis of standard thermionic emission (TE) theory and assuming Gaussian distribution (single) of barrier height. Findings are investigated to explore TFE-mechanism with high value of characteristic ene...

This paper extends the results of discrete-time averaged model presented before to include the effect of feedback loop in the PWM system. This model provides the exact one-cycle-average (OCA) values of the output signal with the presence of feedback even at low switching frequency. This model also provides the accurate OCA values considering non-ideality in the switching stage components. In ad...

The Time-Interleaved Analog-to-Digital Converter (TI-ADC) is an efficient approach to systems requiring very high sampling rate with medium to high resolution. However, interchannel mismatches and process variations appear as a main bottleneck leading to substantial degradation in global TI-ADC performance. In this paper, an adaptive compensation technique is proposed for improving the overall ...

Boiling points have been determined at 101.33 kPa for the binary mixtures of sulfolane + o-xylene, sulfolane + m-xylene, sulfolane+p-xylene, sulfolane+ethylbenzene and sulfolane+1,2,4-trimethylbenzene. Calculations of the non-ideality of the vapor phase were made with the second virial coefficients evaluated from the Hayden–O’Connell method. The binary parameters for five activity coefficient m...

Current-mode (CM) and voltage-mode (VM) multiphase sinusoidal oscillator (MSO) structures using current backward transconductance amplifier (CBTA) are proposed. The proposed oscillators can generate n current or voltage signals (n being even or odd) equally spaced in phase. n+1 CBTAs, n grounded capacitor and a grounded resistor are used for nth-state oscillator. The oscillation frequency can b...

In this work, structural and dynamical properties of the binary mixture of 1-ethyl-3-methyl-imidazolium chloride and 1-ethyl-3-methyl-imidazolium thiocyanate are investigated from ab initio molecular dynamics simulations and compared to the pure ionic liquids. Furthermore, the binary mixture is simulated with two different densities to gain insight into how the selected density affects the diff...

Protein environments substantially influence the balance of molecular interactions that generate structural stability. Transmembrane helices exist in the relatively uniform low dielectric interstices of the lipid bilayer, largely devoid of water and with a very hydrophobic distribution of amino acid residues. Here, through an analysis of bacteriorhodopsin crystal structures and the transmembran...
