TL;DR: In this paper, a temperature sensor based on rare earth fiber peanut (this paperP) shape structure in fiber ring laser (FRL) was proposed and demonstrated, and the sensitivity of refractive index (RI) was measured to further verify the sensing performance of MZI.
Proceedings ArticleDOI
A 90nm CMOS bio-potential signal readout front-end with improved powerline interference rejection
TL;DR: Simulation results showed that the RFE is capable of tolerating a differential electrode offset up to ±50mV, while achieving 140dB CMRR and 51.4nV/√Hz inputreferred noise density.
Journal ArticleDOI
A 0.45 V 147–375 nW ECG Compression Processor With Wavelet Shrinkage and Adaptive Temporal Decimation Architectures
TL;DR: A real-time electrocardiogram (ECG) data compression processor with improved energy efficiency while maintaining high accuracy and real- time operation is presented.
Proceedings ArticleDOI
Hardware-accelerated implementation of EMD
TL;DR: A hardware accelerated HHT system based on Field Programmable Gate Array (FPGA) is presented, which employs hardware and software co-design techniques to effectively improve the processing speed.
Journal ArticleDOI
A Novel Field-Circuit FEM Modeling and Channel Gain Estimation for Galvanic Coupling Real IBC Measurements.
TL;DR: A field-circuit finite element method (FEM) model of galvanic coupling IBC in a real measurement environment to estimate the human channel gain is proposed and results indicated that a circuit module equivalent to external factors can be added to the field- Circuit model, which makes this model more complete.
