The document discusses feedback amplifiers and provides several examples:
1. Feedback in amplifiers improves performance by automatically controlling output levels and reducing gain compared to open-loop amplifiers.
2. Negative feedback is commonly used to stabilize gain, reduce distortion, and increase bandwidth. It is applied by connecting part of the output back to the input.
3. Current feedback amplifiers have advantages over voltage feedback amplifiers like very high input impedance but also limitations that some engineers refuse to use them.
