Noise behavior of negative feedback amplifiers

Noise performance of feedback amplifiers

In general, insertion of impedances in series and/or in parallel with the signal path should be avoided. They increase:

  • Energy storage and power losses

  • Noise

Presentation

The presentation “Influence of Feedback Networks on Noise Performance of Negative Feedback Amplifiers” shows that detrimental effects caused by impedances in the feedback networks can be kept low.
