Finite-time thermodynamics is illustrated by some examples of process optimalization. The objective is minimum entropy production during an electrical process, i.e. the charging of a capacitor. Non-linear electronic processes are investigated in particular, because of their importance in computers and displays.

The capacitance of a parallel plate capacitor is formulated in basic electrostatics, assuming that the separation between the two electrode plates is very narrow and the fringe field of the edges is negligible. However, in practical problems of electrical and electronic engineering there are many cases where the plate separation is wide and the fringe field effect cannot be neglected. In our pr...

The invention of the battery can be attributed to Alessandro Volta (1745-1827) of Como, Italy, who in 1800 described an assembly consisting of plates of two different metals, such as Zn and Cu, placed alternately in a stack-like fashion separated by paper soaked in an aqueous solution, such as brine or vinegar. As discovered by Volta, this contraption was capable of producing an electrical shoc...

The chemical structure and electrical properties of anodized titania are investigated for their application as conformal ultra-thin dielectrics on high surface area titanium electrodes. The chemical structure is studied by XPS depth profiling for the first time along with the role of anodization conditions on dielectric thickness, leakage current, and capacitance densities. Different leakage cu...

In this paper two ultra high speed carbon nanotube FullAdder cells are presented. First design uses two transistors, two resistors and seven capacitors and the second one uses four transistors and seven capacitors. The first design is faster and the second one consumes less power. Simulation results illustrate significant improvement in terms of speed and Power-Delay Product (PDP).

This paper is aimed at demonstrating the high capabilities of KTa0.5Nb0.5O3 thin films for microwave agility applications. Tunable capacitors, resonators and phase shifters were realized with KTN materials. Their high frequency measurements showed, in particular, the very high tuning factors of these films under quite low electric field. Index Terms Ferroelectrics, Interdigital Capacitors, Phas...

BACKGROUND Phase-2 voltage and maximum pulse width are dependent on phase-1 pulse characteristics in a single-capacitor biphasic waveform. The use of 2 separate output capacitors avoids these limitations and may allow waveforms with lower defibrillation thresholds. A previous report also suggested that the optimal tilt may be >70%. This study was designed to determine an optimal biphasic wavefo...
