CMOS operational amplifier design for industrial and biopotential applications: Comprehensive review and circuit implementation

Results in Engineering, Journal Year: 2024, Volume and Issue: 22, P. 102357 - 102357

Published: June 1, 2024

This paper provides a detailed exploration of CMOS operational amplifiers (Op-Amps) aimed at enhancing understanding their development, design, and application. To achieve this, comprehensive examination the common characteristics, parameters, bibliographic reviews Op-Amps, distinguishing among various chosen amplifiers. A review amplifier's keywords between 2008 2018 has also been conducted. bibliometric analysis 4997 documents from Web Science (WOS) Collection is conducted using VOSviewer software. Furthermore, an comparison these Op-Amps across functional aspects relevant to industrial biomedical applications, emphasising salient characteristics each technique. After survey, novel Op-Amp design proposed, incorporating differential amplifier first stage, along with compensating capacitor high gain stage. The biasing circuitry replaced active load resistor (MOS transistor), simplifying layout reducing area power consumption compared traditional two-stage designs. source for this 3.3V. designed achieved 62.9449 dB, CMRR 92.8079 unity bandwidth 33 MHz, optimised 0.001476 . proposed circuit was simulated utilising Cadence Virtuoso 180nm process. simulation results show that desired criteria have met. Additionally, challenges future possibilities in analog circuits, laying groundwork research both analogue digital circuits tackle complex real-world issues addressed.

Biaxial porosity gradient and cell size adjustment improve energy absorption in rigid and flexible 3D-printed reentrant honeycomb auxetic structures

Results in Engineering, Journal Year: 2024, Volume and Issue: 22, P. 102249 - 102249

Published: May 9, 2024

This paper compares different uniaxial and biaxial graded designs of auxetic reentrant honeycomb structures to enhance their mechanical properties, especially the specific energy absorption under compressive load. The lattice were 3D printed using vat photopolymerization masked-stereolithography technique from two materials – tough (OR) flexible (FR). results evaluated a material structural point view, investigating effect porosity, cell number, size, design, fracture mode. universally best energy-absorbing performance was found in biaxially structure with center-wise location highest local porosity. Depending on used resin, its capacity up 2–3 times enhanced compared reference uniform-porosity design. presented data constitutes fundamental understanding identifies practical approaches for tuning structures' regarding response. Finally, this study demonstrates potential shape versatility offered by printing other additive manufacturing techniques.

Synthesis of modified silica gel supported silver nanoparticles for the application of drinking water disinfection: A review

Results in Engineering, Journal Year: 2024, Volume and Issue: 22, P. 102261 - 102261

Published: May 12, 2024

Water treatment technology is advancing to extend the supply of pure drinking water low-income societies. The application biomass-based silver nanoparticles for purification among outstanding innovations in this respect. Silver has less reactivity and excellent stability, which makes it preferable biological applications such as water. In research review, synthesis (AgNPs) using different techniques chemical synthesis, physical photochemical was discussed. AgNPs supported by biomass-driven silica gel its were found be promising technologies. use biobased aerogel disinfection recently been subject findings an effective method killing microorganisms from characteristics bio-silica are unequalled, large part because increased porosity, greater surface area, extraordinarily inadequate thermal conductivity density, potent antibacterial action against both Escherichia coli (E. coli) Staphylococcus aureas (S. aureus) at low concentrations. These features exhibited that bio-based aerogel-coated a interest also have anti-fouling properties prevent clogging membrane filters, enhances their potential improving quality safety.
