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

open access: yes, 2010
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.

The scale matters: A review on stimuli‐responsive microrobots categorized by scale for biomedical applications

open access: yesResponsive Materials, EarlyView.
We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...

A Wide Dynamic Range CMOS Image Sensor with a Charge Splitting Gate and Two Storage Diodes

open access: yesSensors, 2019
In this paper, a wide dynamic range (WDR) CMOS image sensor (CIS) with a charge splitting gate (SG) and two storage diodes (SDs) is presented. By using single-gate on/off control with the SG, photocurrent path to the first (SD1) or second storage diodes (

In-Pixel Temperature Sensors with an Accuracy of ±0.25 °C, a 3σ Variation of ±0.7 °C in the Spatial Domain and a 3σ Variation of ±1 °C in the Temporal Domain

open access: yesMicromachines, 2020
This article presents in-pixel (of a CMOS image sensor (CIS)) temperature sensors with improved accuracy in the spatial and the temporal domain. The goal of the temperature sensors is to be used to compensate for dark (current) fixed pattern noise (FPN ...

Reactivity of the Iron Complexes with the Macrocyclic Ligand 5,5,7,12,12,14‐Hexamethyl‐1,4,8,11‐Tetraazacyclotetradecane (tet) Toward Dioxygen

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The complex [(tet a)FeII(OTf)2] reacts with dioxygen first to a superoxido intermediate and in a consecutive reaction to the corresponding iron–oxido complex. The reactions of the iron complexes [(tet a)FeII(OTf)2] and [(tet b)FeII](OTf)2 (tet = 5,5,7,12,12,14‐hexamethyl‐1,4,8,11‐tetraazacyclotetradecane) with dioxygen were investigated.

Low-Noise and High-Efficiency Near-IR SPADs in 110nm CIS Technology [PDF]

open access: yes, 2019
Photon detection at longer wavelengths is much desired for LiDAR applications. Silicon photodiodes with deeper junctions and larger multiplication regions are in principle more sensitive to near-IR photons.

Mobile electromagnetic levitator for time‐resolved in situ X‐ray diffraction studies of high‐temperature phase transformations

open access: yesJournal of Synchrotron Radiation, EarlyView.
A mobile electromagnetic levitator combined with time‐resolved synchrotron X‐ray diffraction enables in situ studies of high‐temperature phase transformations without container‐induced contamination and reveals the first direct observation of metastable phase formation in undercooled Fe–Co alloys.In situ observations of high‐temperature transformations,
