Explains how to bias a transistor stage so the operating point does not depend much on the device's beta, using feedback.
Recommended as a Signal Path tutorial that designs and measures a single transistor common emitter amplifier, pitched as a fairly basic introduction to class A gain stages.
Recommended for working through BJT voltage divider bias calculations, including replacing the base network with its Thevenin equivalent before analysing an amplifier.
