#185: Back to Basics: Bipolar Transistor bias circuits and Beta dependence
Why people recommend it
Explains how to bias a transistor stage so the operating point does not depend much on the device's beta, using feedback.
Watch for: Posted by the video's own author; assumes basic transistor knowledge
In their words
This is Another video which I referred to understand the biasing of transistors when they need to be used as amplifiers
