This article showcases the advantages of an op amp loop-stability analysis method that I use myself and recommend to others. This method looks at the behavior and rate of closure of the open-loop gain ...

Feedback refers to a core concept in circuit design and control theory, used to stabilize amplifiers and control system behavior. This article outlines the fundamental architecture of feedback, ...

This month’s Tune-Up column, which concludes a three-part series on position loops, addresses feed-forward gains. Motion control systems often use feed forward to speed up the response to rapidly ...

Switching power supplies rely on feedback control loops to ensure that the required voltage and current are maintained under varying load conditions. Design of the feedback control loop influences ...

The popular FDA comes in both Current Feedback Amplifier (CFA) and Voltage Feedback Amplifier (VFA) variants. The CFA versions tend to be used in AC-coupled applications where their great full power ...

For the PDF version of this article, click here. Most offline and telecom power supplies need a method to isolate the relatively high input voltage from lower voltage outputs to provide safety, ...
