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 0.38-pJ/step Pulse-Width Locked Time-Domain Wheatstone Bridge Sensor Readout IC for LIG-Based Wearable Strain Sensing System

A 0.38-pJ/step Pulse-Width Locked Time-Domain Wheatstone Bridge Sensor Readout IC for LIG-Based Wearable Strain Sensing System 150 150
Author(s): Siyuan Xu, Longhuang Li, Yiyang Du, Huiru Yang, Huaiyu Ye, Huan Hu

Abstract:

This article presents a pulse-width locked-loop (PWLL) time-domain readout integrated circuit (IC) for wearable strain-sensing systems based on a laser-induced graphene (LIG) strain sensor. A time-domain Wheatstone bridge (WhB) architecture is proposed, incorporating a duty-cycled resistor (DCR) and a voltage-controlled oscillator (VCO)-based integrator to realize a digitally intensive, energy-efficient, …

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 …
