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 ...

Signals released by immune cells during a bout of inflammatory bowel disease interfere with intestinal cells' ability to regenerate. Yet people with inflammatory bowel diseases have a higher risk of ...

Feedback loops play an important role in all aspects of life. Basic human physiology, for example, relies on feedback to maintain a safe environment. Feedback loops influence our behavior, and many ...
