A solution for linearity, stability and frequency bandwidth in PAM electrocutaneous stimulators' isolation interface
(Butterworth-heinemann LtdOxfordInglaterra, 1996)
A high input impedance single-ended input to balanced differential output amplifier
(Institute of Electrical and Electronics Engineers, 2019-05)
A high input impedance circuit to convert a single-ended (SE) voltage to its differential counterpart is proposed. It allows setting the common-mode (CM) output voltage to a reference voltage vR, while providing gain and ...
A new parallel and decomposition approach to solve the medium- and low-voltage planning of large-scale power distribution systems
(2021-11-01)
The world energy demand is increasing. Currently, most electricity generation sources are fossil fuels. In recent years, the global energy matrix for power generation is changing, in order to meet the demand with minimal ...
A multi-loop voltage-feedback filterless class-D switching audio amplifier using unipolar pulse-width-modulation

Low-Frequency Noise in Field-Effect Devices Functionalized With Dendrimer/Carbon-Nanotube Multilayers
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)
Low-frequency noise in an electrolyte-insulator- semiconductor (EIS) structure functionalized with multilayers of polyamidoamine (PAMAM) dendrimer and single-walled carbon nanotubes (SWNT) is studied. The noise spectral ...
Solution of the Optimal Reactive Power Flow Problem Using a Discrete-Continuous CBGA Implemented in the DigSILENT Programming Language
(Cartagena de Indias, 2021-11-12)
The problem of the optimal reactive power flow in transmission systems is addressed in this research from the point of view of combinatorial optimization. A discrete-continuous version of the Chu & Beasley genetic algorithm ...
Stability Analysis of Single-Phase Low-Voltage AC Microgrids With Constant Power Terminals
(Institute of Electrical and Electronics Engineers, 2019-07)
This express brief presents the stability analysis of single-phase microgrids (SP-MG) operating under master-slave connection with constant power terminals. The SP-MG is composed of linear elements, nonlinear loads and ...
