A 6-bit Serializer With Integrated Manchester Encoder Using Flexible a-IGZO TFT Technology

A 6-bit Serializer With Integrated Manchester Encoder Using Flexible a-IGZO TFT Technology 150 150
Author(s): Suyash Shrivastava, Pydi Ganga Bahubalindruni

Abstract:

This article presents an experimental characterization of a novel 6-bit parallel-to-serial data converter integrated with a Manchester encoder. The system comprises an on-chip digital logic block that generates six mutually nonoverlapping control signals ( $\phi _{0-5}$ ) and three 120° phase-shifted clock signals to drive the switching transistors in the serializer and the …

A Single-Lead ECG Wearable Sensor With 1.04 s Latency for Cardiac and Biometric Detection Tasks

A Single-Lead ECG Wearable Sensor With 1.04 s Latency for Cardiac and Biometric Detection Tasks 150 150
Author(s): Yuxin Ji, Chao Wang, Yuzhi Hao, Yang Zhao, Jian Zhao, Mingyi Chen, Guoxing Wang, Yong Lian, Yongfu Li

Abstract:

The wearable electrocardiogram (ECG) sensor has immense potential for cardiovascular healthcare monitoring. However, uploading ECG signals to server-side devices for diagnosis poses privacy risks. Multi-tasking ECG processors rely on multi-beat windows and complex models, leading to high latency and energy consumption that limit deployment in resource-constrained wearable devices. In this …

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 …
