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... |
