Scintillation breakdowns in tantalum capacitors

Scintillations in tantalum capacitors are momentarily local breakdowns terminated by a self-healing, or conversion of the manganese oxide used as a cathode to a high-resistive mode. Similar breakdown events are often considered as nuisances, rather than failures. The author argues that a...

Improved signal to noise ratio of electro-ultrasonic spectroscopy

The paper presents signal to noise consideration of a new NDT method. Tested sample is excited by electrical and ultrasonic signals with different frequencies. On the defect new harmonic signal is created with frequency given by subtraction of exciting frequencies fE and fU. High&#...

Comparison of Simulation of a linear transmission line with the nonlinear load

The paper deals with the numerical modeling of voltage and current waveforms on transmission lines with nonlinear loads. It will be considered the linear transmission line only. The propagation of the voltage and current waveforms is solved numerically in the time domain. The new&#...

Design of the 1.5 and 2.5 Bit MDAC - application opportunities

The paper presents design and simulation of the most important stage in pipelined analog-to-digital converter (ADC) so-called multiplying digital-to-analog converter (MDAC). The MDAC with 1,5 and 2,5 bit of resolution were designed using CMOS 0.7 μm technology. The both types of MDAC we...

Third harmonic index as a diagnostic tool of high-voltage varistors

High voltage varistors that consist of grained ZnO have to be tested before assembling. The recommended method for standard industrial testing of varistors demands application of high voltages and intensive currents that is inconvenient and needs extensive power consumption. This method requ...

Application of short circuit waveguide method for evaluation of inhomogenities in dielectric sample

In the paper main consideration is paid to investigation of inhomogenities in dielectric sample from the standpoint of their impedance properties and reflected signal amplitude. Such application include inspecting modern materials such as composites, detecting and characterizing surface and volume...

Investigation and Implementation of Test Vectors for Efficient IC Analysis

Up until now, the efficient and structured analysis of unknown CMOS integrated circuits (ICs) has become a topic of great relevance. In the last decade different invasive and non-invasive strategies have been developed to analyse unknown ICs. However, invasive procedures always lead to&...

Transient and sensitivity analysis at semi-discrete multiconductor transmission line models

The paper deals with methods for the solution of transient phenomena and sensitivities at semi-discrete models of multiconductor transmission lines (MTL). The models are formed by a cascade connection of generalized lumped-parameter Π networks, they can be fed in arbitrary nodes, nonzero...
