A Voltage Gain-Controlled Modified CFOA And Its Application in Electronically Tunable Four-Mode All-Pass Filter Design
(International Science & Engineering Society, o.s., 2012-10-31)
This paper presents a new active building block (ABB) called voltage gain-controlled modified current feedback amplifier (VGC-MCFOA) based on bipolar junction transistor technology. The versatility of the new ABB is ...
Study of Small-signal Model of Simple CMOS Amplifier with Instability Compensation of Positive Feedback Loop
(De Gruyter Open, 2015-07-06)
The paper deals with precise analysis of simple AC variable gain CMOS amplifier. The circuit can be used as a simple voltage follower (6 MOS transistors are required) or amplifier. The main attention of this work is focused ...
Measurements of Ultra Wide Band In-vehicle channel - statistical description and TOA positioning feasibility study
(Springer, 2015-08-11)
This paper reports on a real-world wireless channel measurement campaign for
in-vehicle scenarios in the ultra wide bandwidth (UWB) frequency range of
3-11 GHz. The effects of antenna placement in the vehicle's ...
Design of the simple oscillator with linear tuning and pi/4 phase shift based on emulator of the modified current differencing unit
(The Institute of Electronics, Information and Communication Engineers (IEICE), 2015-10-10)
This paper presents a simple oscillator with 45 degrees phase shift between output signals. A Modified current Differencing Unit (MCDU) was used for its design. The MCDU offers controllability of input resistances ...
Lagrangian for circuits with higher-order elements
(MDPI, 2019-10-29)
The necessary and sufficient conditions of the validity of Hamilton’s variational principle for circuits consisting of (alpha,beta) elements from Chua’s periodical table are derived. It is shown that the principle holds ...
About v-i Pinched Hysteresis of Some Non-Memristive Systems
(Hindawi, 2018-09-24)
A special subset of two-terminal elements providing pinched hysteresis loops in the voltage-current plane with the lobe area increasing with the frequency is analysed. These devices are identified as non-memristive systems ...
Hamilton’s principle for circuits with dissipative elements
(Hindawi, 2019-10-28)
The classic form of Hamilton’s variational principle does not hold for circuits with dissipative elements. It is shown in the paper that this may not be true in the case of systems consisting of the so-called higher-order ...
New Resistorless and Electronically Tunable Realization of Dual-Output VM All-Pass Filter Using VDIBA
(Springer, 2013-01-07)
In this paper, a new active element called voltage differencing inverting buffered amplifier (VDIBA) is presented. Using single VDIBA and a capacitor, a new resistorless voltage-mode (VM) first-order all-pass filter (APF) ...
New resistorless tunable voltage-mode universal filter using single VDIBA
(Springer, 2013-08-01)
To increase the universality of the recently introduced voltage differencing inverting buffered amplifier (VDIBA), this letter presents a new voltage-mode (VM) multi-input–single-output (MISO) universal filter. The proposed ...
Multivariate classification of echellograms: a new perspective in Laser-Induced Breakdown Spectroscopy analysis
(Springer Nature, 2017-12-01)
In this work, we proposed a new data acquisition approach that significantly improves the repetition rates of Laser-Induced Breakdown Spectroscopy (LIBS) experiments, where high-end echelle spectrometers and intensified ...
