A Fully Integrated Counter Flow Energy Reservoir for Peak Power Delivery in Small Form-Factor Sensor Systems

Kyojin Choo, Yao Shi

We present a fully integrated energy reservoir unit using a counter flow method for peak power delivery in space-constrained sensor systems. Recent advances in circuits have enabled significant reduction in the size of wireless systems such as implantable ...

A transparent silk-fibroin-based triboelectric microgenerator for airflow energy harvesting

Jürgen Brugger, Xiao Sheng Zhang, Ya Wang, Yinben Guo

We present a new transparent high-performance triboelectric microgenerator (TEMG) based on an emerging material, silk fibroin. Silk fibroin has a strong ability to lose electrons and occupies a top-level positive position in the triboelectric series. It th ...

High frequency self-oscillating current switching for a fully integrated fail-safe stimulator output stage

Alexandre Schmid, Reza Ranjandish

Using blocking capacitors in biomedical stimulators is important to the safety of the developed systems. However, the capacitors should be large enough in order to minimize the required voltage headroom. On the other hand, integrating large capacitors of f ...

IEEE2016

Recent advances in circuits have enabled significant reduction in the size of wireless systems such as implantable biomedical devices. As a consequence, the battery integrated in these systems has also shrunk, resulting in high internal resistances (~10kΩ) ...

A 3.1 mW 8b 1.2 GS/s Single-Channel Asynchronous SAR ADC With Alternate Comparators for Enhanced Speed in 32 nm Digital SOI CMOS

Yusuf Leblebici, Lukas Kull, Thomas Toifl

An 8b 1.2 GS/s single-channel Successive Approximation Register (SAR) ADC is implemented in 32 nm CMOS, achieving 39.3 dB SNDR and a Figure-of-Merit (FoM) of 34 fJ per conversion step. High-speed operation is achieved by converting each sample with two alt ...

The effect of fractionality nature in differences between computer simulation and experimental results of a chaotic circuit

Salman Faraji

In practice, some differences are usually observed between computer simulation and experimental results of a chaotic circuit. In this paper, it is tried to obtain computer simulation results having more correlation with those obtained in practice by using ...
