A dither‐less bit weight digital background calibration for bridge capacitor digital‐to‐analog converter successive approximation register analog‐to‐digital converters

open access: yesElectronics Letters, 2022
The authors present a dither‐less background digital bit weights calibration method for split‐capacitor digital‐to‐analog converter (CDAC) successive approximation register (SAR) analog‐to‐digital converters (ADCs) to improve non‐linearities caused by ...

Controlling Grain Growth in Powder Bed Fusion of Yttria‐Stabilized Zirconia Using Femtosecond Lasers: Challenges and Methodological Insights

open access: yesAdvanced Engineering Materials, EarlyView.
Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

Digital OFDM-PON Based on Delta–Sigma Modulation Employing Binary IM-DD Channels

open access: yesIEEE Photonics Journal, 2017
In this paper, a delta–sigma modulation is proposed for the orthogonal frequency division multiplexed-passive optical network (OFDM-PON) to enable transmission of OFDM signals via binary intensity modulation and direct detection (IM-DD) channels ...

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

open access: yesAdvanced 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.

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

A 10-Bits 50-MS/s SAR ADC Based on Area-Efficient and Low-Energy Switching Scheme

open access: yesIEEE Access, 2020
This paper presents a 10-bits successive approximation register analog-to-digital converter (SAR ADC) for low-power applications. The input signals are multiplied by two because the dual sampling technique is used during the sampling phase.

Photonic analog-to-digital converters

open access: yesOptics Express, 2007
This paper reviews over 30 years of work on photonic analog-to-digital converters. The review is limited to systems in which the input is a radio-frequency (RF) signal in the electronic domain and the output is a digital version of that signal also in the electronic domain, and thus the review excludes photonic systems directed towards digitizing ...
