Faculty, Department of E&C Engg., MIT . Types of feedback. There are two types of feedback in amplifiers:. Positive feedback(regenerative feedback). Negative feedback(degenerative feedback). Jeff Larkin. <larkin@cray.com>. Cray XE6 Tuning Top 10. For most users and applications, using default settings work very well. For users who want to experiment to get the best performance they can, the following presentation gives you some information on compilers and settings to try.
