A 4-μW Bandwidth/Power Scalable Delta-Sigma Modulator Based on Swing-Enhanced Floating Inverter Amplifiers

This article presents a fully dynamic scalable switched-capacitor delta-sigma modulator that achieves a 94.1-dB dynamic range (DR). Power-and- bandwidth scalability by only changing the clock frequency is achieved using a capacitively biased and swing-enhanced floating inverter operational transconductance amplifier (OTA). Fabricated in a 180...

Effect of Nano-SnS and Nano-MoS₂ on the corrosion protection performance of the polyvinylbutyral and zinc-rich polyvinylbutyral coatings

In this paper, four composite coatings of nano-SnS/polyvinylbutyral (PVB), nano-MoS₂/PVB, nano-SnS-Zn/PVB, and nano-MoS₂-Zn/PVB were prepared, and their anti-corrosion mechanism was analyzed by experimental and theoretical calculations. The results of the electrochemical experiments show that the effect of nano-MoS<sub>2...

Three-dimensional Modeling of Anode-supported Planar SOFC with Direct Internal Reforming

This paper presents a three-dimensional model of an anode-supported planar SOFC with corrugated bipolar plates serving as gas channels and current collector above the active area of the cell, based on the direct internal reforming reaction of methane and the electrochemical reaction of hydrogen. A co-flow system with gas mixture of methane,...
