Engineers use feedback loops — typically negative feedback is more useful, but positive feedback is needed for oscillators.

The most important design parameters in dc/dc power conversion design are the calculations and methodologies involved in feedback loop compensation. When these parameters are not properly calculated, ...

Typical circuits textbooks tell us that there are four basic feedback topologies. The impression is given (if not stated) that a given feedback circuit will conform to one of these four topologies.

A newly identified part of a brain circuit mixes sensory information, memories, and emotions to tell whether things are familiar or new, and important or just "background noise." Led by researchers ...
