Is chronic pain a separate brain function? A new study maps the neurological loop between the spinal cord and cortex that drives persistent pain.

Analyzing a power system's stability usually begins with a look at the open-loop Bode plot of a buck or flyback converter's power stage. From this plot, the designer extracts phase and gain data for ...

Some low-dropout regulators (LDOs) use multiple feedback loops to improve output voltage transient response. In many of these cases, some or all of the loops are inside the IC. Accessing these loops ...

After my last Signal Chain Basics article, The basics of op amp loop-stability analysis: A tale of twin loop-gains, I received questions about how to generate the open-loop SPICE simulation curves ...
