A Two-Stage Fully Differential Inverter-Based Self-Biased CMOS Amplifier With High Efficiency

TL;DR: A two-stage fully differential CMOS amplifier comprising inverters as input structures and employing self-biasing techniques is presented, which achieves the highest efficiency of its class and although it relies on a quasi-class-A topology, it is comparable to class-AB amplifiers.
Proceedings ArticleDOI

Two-stage fully-differential inverter-based self-biased CMOS amplifier with high efficiency

TL;DR: A novel two-stage fully-differential CMOS amplifier comprising two self-biased inverter stages, with optimum compensation and high efficiency, shown that it achieves the highest efficiency of its class and comparable to the best class AB amplifiers.

Stability and magnetic properties of cobalt nitrides

TL;DR: In this paper, the results indicate that the magnetic behavior of the hexagonal nitride is strongly dependent on the nitrogen content and the comparison of the experimental lattice parameters and magnetization values with the self-consistent density functional theory (DFT) calculations allows to determine the stoichiometry of the prepared compounds.

Measurements of Higgs boson production cross-sections in the H → τ+τ− decay channel in pp collisions at $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

Georges Aad, +2844 more
TL;DR: In this article , measurements of the production cross-sections of the Standard Model (SM) Higgs boson decaying into a pair of τ -leptons are presented, using data collected with the ATLAS detector from pp collisions produced at the Large Hadron Collider at a centre-of-mass energy of = 13 TeV.
