Journal ArticleDOI
A Thermal/RF Hybrid Energy Harvesting System With Rectifying-Combination and Improved Fractional-OCV MPPT Method
TL;DR: The shorter sampling time of 26ms every 16s for the proposed FOCV MPPT method reduces the long charging tail required to refresh the sampling capacitor, resulting in a an improved average efficiency of 82.2% for the thermal harvester.
Journal ArticleDOI
A 1.8 $\mu$ W −65 dB THD ECG Acquisition Front-End IC Using a Bandpass Instrumentation Amplifier With Class-AB Output Configuration
TL;DR: This brief presents a power-efficient, highly linear front-end (FE) integrated circuit (IC) for electrocardiogram (ECG) acquisition applications that is capable of detecting high-fidelity ECG waveforms.
Journal ArticleDOI
A −68 dB THD, 0.6 mm 2 Active Area Biosignal Acquisition System With a 40–320 Hz Duty-Cycle Controlled Filter
TL;DR: In real-time Electrocardiogram (ECG), Electromyography (EMG), and Electroencephalography (EEG) measurements, high-fidelity waveforms are acquired using the proposed FE IC, validating the system’s reconfigurability and high-linearity.
Journal ArticleDOI
An RF-DC Converter IC With On-Chip Adaptive Impedance Matching and 307- $\mu$ W Peak Output Power for Health Monitoring Applications
TL;DR: Results show that the impedance tuning mechanism can extend the optimal frequency range where the efficiency is higher than 80% of its peak value from 150 MHz (800–950 MHz) for the case without tuning to 220 MHz (780 MHz–1 GHz) when the impedance is adjusted using the control loop.
Proceedings ArticleDOI
An RF powering system with adaptive impedance matching for individual health monitoring applications
TL;DR: A novel tuning mechanism is proposed to automatically adjust the impedance of the matching network, which can effectively improve the power efficiency of the system by 47% compared to the case without tuning.
