Implementation of a Low Noise Amplifier With Self-Recovery Capability

IEEE Access, 2019
In this paper, an RF low noise amplifier (LNA) with self-recovery capability has been designed and implemented. A degradation model of hot carrier injection (HCI) of n-channel MOSFETs is proposed to simulate the aging process of the RF circuits, and a ...

ε-iron nitrides: Intrinsic anomalous Hall ferromagnets

APL Materials, 2015
The anomalous Hall effect in ε-iron nitrides (ε-Fe3-xN, 0 ≤ x ≤ 1) has been systematically investigated taking advantage of the fact that the exchange splitting of ε-Fe3-xN can be continuously tuned through the nitrogen concentration.

Functional thin films on surfaces

Proceedings of the 14th ACM SIGGRAPH / Eurographics Symposium on Computer Animation, 2015
The motion of a thin viscous film of fluid on a curved surface exhibits many intricate visual phenomena, which are challenging to simulate using existing techniques. A possible alternative is to use a reduced model, involving only the temporal evolution of the mass density of the film on the surface.

Lattice structure and magnetization of LaCoO3 thin films

, 2010
We investigate the structure and magnetic properties of thin films of the LaCoO$_{3}$ compound. Thin films are deposited by pulsed laser deposition on various substrates in order to tune the strain from compressive to tensile. Single-phase (001) oriented
