The Impact of Magnetic Field on Defective FDSOI and FinFET Devices

The Impact of Magnetic Field on Defective FDSOI and FinFET Devices 150 150
Author(s): Munazza Sayed, Hussam Amrouch

Abstract:

This article explores the efficacy of a unique defect detection mechanism for the FinFET and FDSOI transistors: magnetomodulation of drain current. Using multiphysics technology CAD (TCAD), we model the impact of static and transient magnetic fields on drain current in the following defect-free and defective devices: 1) FDSOI with interface trap …

An 18.3-μW 108.3-dB DR Discrete-Time Delta-Sigma Modulator Using a Loop Filter Auto-Shift Technique

An 18.3-μW 108.3-dB DR Discrete-Time Delta-Sigma Modulator Using a Loop Filter Auto-Shift Technique 150 150
Author(s): Cong Wei, Ziqiang Peng, Lijie Huang, Jinze Lai, Rongshan Wei, Xiaoqiang Lu, Zhichao Tan

Abstract:

This article presents a discrete-time, third-order, single-loop, 17-level delta-sigma modulator (DSM) for high-dynamic-range sensor measurement applications, which employs a loop filter auto-shift (LFAS) technique. It uses an on-chip 1.5-bit Schmitt monitor to determine whether the input amplitude is large or small. The DSM automatically shifts to loop filter A for …

High-Precision Close-to-Analog Programming of PCM Cells as Devices for AiMC Edge-AI

High-Precision Close-to-Analog Programming of PCM Cells as Devices for AiMC Edge-AI 150 150
Author(s): Alessio Antolini, Andrea Lico, Francesco Zavalloni, Lorenzo Greco, Riccardo Zurla, Jacopo Bertolini, Riccardo Vignali, Luca Iannelli, Emanuela Calvetti, Marco Pasotti, Alessandro Cabrini, Eleonora Franchi Scarselli

Abstract:

This article presents a high-precision close-to-analog programming methodology for phase-change memory (PCM) cells, targeting analog in-memory computing (AiMC) architectures for edge-artificial intelligence (AI) applications. By leveraging an iterative accumulation approach during the verify phase, the proposed technique enhances the effective number of bits (ENOBs) achievable in PCM cells. Experimental validation …

An Ultralow Cross-Regulation Single-Inductor Multiple-Output (SIMO) Buck Converter Using Reordered Power-Distributive Control

An Ultralow Cross-Regulation Single-Inductor Multiple-Output (SIMO) Buck Converter Using Reordered Power-Distributive Control 150 150
Author(s): Baochuang Wang, Xiaonan Wu, Minghao Shang, Lin Cheng

Abstract:

A single-inductor multiple-output (SIMO) buck converter employing reordered power-distributive control (RPDC) is presented to achieve ultralow cross regulation. Adedicated power-distribution controller implements RPDC by adaptively adjusting the switching sequence: when the inductor current is insufficient, the switching period is extended, and when excessive, an end phase in the form of …

An 8.62-μW 75-dB DRSoC Fully Integrated SoC for Spoken Language Understanding

An 8.62-μW 75-dB DRSoC Fully Integrated SoC for Spoken Language Understanding 150 150
Author(s): Sheng Zhou, Zixiao Li, Longbiao Cheng, Jérôme Hadorn, Chang Gao, Qinyu Chen, Tobi Delbruck, Kwantae Kim, Shih-Chii Liu

Abstract:

We present a sub-10- $\mu $ W fully integrated SoC for on-device spoken language understanding (SLU). Its analog feature extractor (FEx) applies global and per-channel automatic gain control (AGC) to extend the system’s dynamic range (DR)—a critical requirement for real-world scenarios, including far-field operations. The on-chip streaming-mode recurrent …
