When the ultra high voltage (UHV) substation used the gas insulated switchgear (GIS) system to switch lines with capacitive current, the pre-breakdown and multiple reignition will occur between switching contacts. Because of discharge characteristics of SF6 and special structures of GIS system, the variations of the electromagnetic transient process and very fast transient overvoltage (VFTO) ar...
Thermal noise and 1/f noise are known to exist in carbon composition (CC) and thick film (TF) resistors. A circuit involving a differential instrumentation op-amp was used to measure the noise of a resistor under test. The noise spectra of these resistors were measured using a dynamic signal analyzer that performs an auto-correlation Fourier transform from the time domain to the frequency domai...
BACKGROUND In type 1 diabetes (T1D), adjuvant treatment with inhibitors of the renin-angiotensin-aldosterone system (RAAS), which dilate the efferent arteriole, is associated with prevention of progressive albuminuria and renal dysfunction. Uncertainty still exists as to why some individuals with long-standing T1D develop diabetic kidney disease (DKD) while others do not (DKD resistors). We hyp...
Abstract The temperature coefficient of resistors is one the key parameters to characterize reliability resistors. In precision circuit design, it necessary test and screen use with matching values ensure accuracy stability output. this paper, aiming at how accurately value low-temperature resistors, an indirect method proposed. study adds a reference resistor into loop tests voltage both ends ...
A new CCII-based circuit for the simulation of mutually coupled circuits is presented. The circuit uses six commercially available plus-type secondgeneration current conveyors (CCIIþs), six resistors and two grounded capacitors. The primary self-inductance, the secondary self-inductance and the mutual inductance can be independently controlled using three different resistors. SPICE simulation r...
Este artigo aborda as contribuições da Nova Teoria Comunicação (NTC) no escopo compreendida em sua maioridade, como Ciência. Levada a cabo por Ciro Marcondes Filho (*1948-†2020), NTC privilegia o metáporo procedimento de pesquisa científica. De acordo com epistemologia metapórica, comunicação é um fenômeno raro, impossível ser capturada métodos científicos tradicionais e pressupõe uma abertura ...
This work presents a process design kit (PDK) for 0.15 μm GaAs pHEMT low-noise MMIC applications developed AWR Microwave Office (MWO). A complete set of basic elements is proposed, such as TaN thin film resistors and mesa-resistors, capacitors, inductors, transistors. The PDK can be used in technology transfer or education.
The elementary 2-terminal network consisting of a resistively (R−) shunted inductance (L) in series with a capacitatively (C−) shunted resistance (R) with R = √ L/C, is known for its non-dispersive dissipative response, i.e., with the input impedance Z0(ω) = R, independent of the frequency (ω). In this communication we examine the properties of a novel equivalent network derived iteratively fro...
