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...

Developing AI into explanatory supporting models: An explanation-visualized deep learning prototype

Using Artificial Intelligence (AI) and machine learning technologies to automatically mine latent patterns from educational data holds great potential to inform teaching and learning practices. However, the current AI technology mostly works as "black box"-only the inputs and the corresponding outputs are available, which largely impedes...

How To Break the Janus Effect of H ₂ O ₂ in Biocatalysis? Understanding Inactivation Mechanisms To Generate more Robust Enzymes

H ₂ O ₂ , is an attractive oxidant for synthetic chemistry, especially if activated as percarboxylic acid. H ₂ O ₂ , however, is also a potent inactivator of enzymes. Protein engineering efforts to improve enzyme resistance against H ₂ O ₂ in the past have mostly focused on...
