High quality-factor and inductance of symmetric differential-pair structure active inductor using a feedback resistance design

Abstract: This paper proposes a new symmetric differential-pair structure for the active inductor. The CMOS spiral inductor occupies a large chip size and is difficult to obtain a high Q-factor. A ...

Physical activity as a protective factor for dementia and Alzheimer’s disease: systematic review, meta-analysis and quality assessment of cohort and case–control studies

Objective Physical activity (PA) is associated with a decreased incidence of dementia, but much of the evidence comes from short follow-ups prone to reverse causation. This meta-analysis investigates ...
