Integrated Spatiotemporal Multiscale- Multiphysics-Uncertainty Simulation for Controlling Variability in RRAM Devices

Integrated Spatiotemporal Multiscale- Multiphysics-Uncertainty Simulation for Controlling Variability in RRAM Devices 150 150
Author(s): Ziyan Liao, Zhiheng Huang, Min Xiao, Yuezhong Meng, Hui Yan, Yang Liu

Abstract:

Resistive random access memory (RRAM) is a leading candidate for next-generation nonvolatile memory and neuromorphic computing. However, its performance is limited by inherent switching variability and uncertainties in spatiotemporal multiscale materials and processes. This study integrates multiphysics and multiscale modeling with uncertainty quantification (UQ) to systematically address these limitations and …

A 4.6 μW, 133-VPP Common-Mode Interference-Tolerant Biopotential Amplifier for Two-Electrode Recording System in 110-nm CMOS

A 4.6 μW, 133-VPP Common-Mode Interference-Tolerant Biopotential Amplifier for Two-Electrode Recording System in 110-nm CMOS 150 150
Author(s): Yongjae Park, Yeong-Jin Mo, Jeong-Hoon Kim, Gert Cauwenberghs, Seong-Jin Kim

Abstract:

This article presents a biopotential recording analog front-end (AFE) specifically tailored for a two-electrode measurement system, capable of capturing small biopotential signals while tolerating a large common-mode interference (CMI) over 130 VPP. By leveraging the Miller effect, the proposed CMI-Follower provides a significantly low common-mode input impedance ( $Z_{\text {IN-CM-C}}$ ), achieving …
