Abstract:

A fully integrated multimodal biosensing system-on-chip (SoC) for stress monitoring is presented. The proposed SoC integrates electrocardiography (ECG), electrochemical (ECH), photoplethysmography (PPG), and galvanic skin response (GSR) sensing together with an on-chip transmitter (TX), wake-up receiver (WuRX), and power-management unit (PMU) for compact, standalone operation. ECG and ECH share a …

Abstract:

This article presents a high-precision tunnel magnetoresistance (TMR)-based non-contact current sensor with enhanced immunity to sensitivity drift. A background sensitivity stabilization loop (SSL) continuously regulates the TMR bias voltage to compensate intrinsic sensitivity variations. Through this closed-loop regulation, sensitivity drift of the TMR sensor induced by temperature, mechanical stress, …
