Design of a 90 GHz SOI Fin Electro-Optic Modulator for High-Speed Applications

Applied Sciences, 2019
Introducing high speed networks, such as the fifth generation of mobile technology and related applications including the internet of things, creates a pressing demand for hardware infrastructure that provides sufficient bandwidth.

Intrapixel effects of CCD and CMOS detectors [PDF]

2017 JINST 12 C04010, 2017
Intrapixel nonuniformity is known to exist in CCD and CMOS image sensors, though the effects in backside illuminated (BSI) CCDs are too small to be a concern for most astronomical observations. However, projects like the Large Synoptic Survey Telescope require precise knowledge of the detector characteristics, and intrapixel effects may need more ...

Overview of CMOS process and design options for image sensor dedicated to space applications [PDF]

, 2005
With the growth of huge volume markets (mobile phones, digital cameras…) CMOS technologies for image sensor improve significantly. New process flows appear in order to optimize some parameters such as quantum efficiency, dark current, and conversion gain.

Ternary Transistors With Reconfigurable Polarities

Advanced Functional Materials, EarlyView.
Polarity‐reconfigurable ternary transistors are demonstrated using black phosphorus homojunction with asymmetric contacts and split‐gate structures. Suppression of majority carrier injection, while Fowler–Nordheim tunneling of low‐density minority carriers persists, enables a well‐defined intermediate state with improved on/off ratios.

CMOS design of cellular APAPs and FPAPAPs: an overview [PDF]

, 2002
CNN-based analog visual microprocessors have similarities with the so-called Single Instruction Multiple Data systems, although they work directly on analog signal representations obtained through embedded optical sensors and hence do not need a frontend

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.

Reducing Average and Peak Temperatures of VLSI CMOS Digital Circuits by Means of Heuristic Scheduling Algorithm [PDF]

Dans 13th International Worshop on THERMal INvestigations of ICs and Systems - THERMINIC 2007, Budapest : Hongrie (2007), 2008
This paper presents a BPD (Balanced Power Dissipation) heuristic scheduling algorithm applied to VLSI CMOS digital circuits/systems in order to reduce the global computational demand and provide balanced power dissipation of computational units of the designed digital VLSI CMOS system during the task assignment stage.

Momentum-driven feedback and the Mass-sigma relation in non-isothermal galaxies [PDF]

, 2012
We solve for the velocity fields of momentum-conserving supershells driven from galaxy centres by steady winds from supermassive black holes or nuclear star clusters (central massive objects: CMOs). We look for the critical CMO mass that allows such a shell to escape from its host galaxy.

Optical Whispering‐Gallery Mode as a Fingerprint of Magnetic Ordering in Van der Waals Layered CrSBr

Advanced Functional Materials, EarlyView.
A novel nanoscale optomagnetic sensing approach is developed using whispering‐gallery mode resonances in a self‐rolled‐up microcavity. This method enables ultra‐sensitive detection of weak magnetism by correlating resonance shifts with magnetic susceptibility.
