Design of an integrated circuit with buried double junction photodiodes for optical immunoassays

Revista Elektrón, 2020
Optical immunoassays require measurement systems capable of distinguishing the light from the laser source, used to illuminate the assay, from the light generated by the particles contained within the assay itself (fluorescence).

A CMOS VLSI cochlea [PDF]

ICASSP-88., International Conference on Acoustics, Speech, and Signal Processing, 2003
An analog electronic cochlea has been built in CMOS VSLI technology using micropower techniques to achieve the goal of usefulness via realism. The key point of the model and circuits is that a cascade of simple, nearly linear, second-order filter stages with controllable Q parameters suffices to capture the physics of the fluid-dynamic traveling-wave ...

RTS noise impact in CMOS image sensors readout circuit [PDF]

, 2009
CMOS image sensors are nowadays widely used in imaging applications even for high end applications. This is really possible thanks to a reduction of noise obtained, among others, by Correlated Double Sampling (CDS) readout.

All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

Advanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry

Advanced Functional Materials, EarlyView.
In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

Analysis and Optimization of Noise Response for Low-Noise CMOS Image Sensors [PDF]

, 2012
CMOS image sensors are nowadays widely used in imaging applications and particularly in low light flux applications. This is really possible thanks to a reduction of noise obtained, among others, by the use of pinned photodiode associated with a ...

Role of Intrinsic Electron Trapping in Negative Charging of Amorphous Alumina

Advanced Functional Materials, EarlyView.
Intrinsic electron trapping in amorphous Al2O3 is examined using hybrid‐DFT models spanning a wide density range. Both spontaneous and thermally activated trapping are identified, with pronounced spontaneous localization in dense, partly crystallized structures.

Recent progress of oxide-TFT-based inverter technology

Journal of Information Display, 2021
Oxide semiconductor-based thin-film transistor (oxide-TFT) technology have gained significant attention since the innovation of n-channel oxide-TFT using ZnO and amorphous In–Ga–Zn–O (a-IGZO) channels because of their superior device properties including
