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...

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&#...

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&#...

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...
