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.

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 ...

Feedback Circuits and Two-Port Blocks, Part 1: From Circuits to Blocks with Ports introduced the concept of the port and applied it to a simple example. In this third part, a feedback circuit example ...

The hysteretic power supply is simpler than the voltage- or current-mode closed-loop-control dc-dc switchers, although its simplicity may be a bit deceiving due to component variations and potential ...
