BIPOLAR TRANSISTOR BIAS CIRCUITS AND BETA DEPENDENCE

This tutorial back-to-basics video discusses the operating point (or quiescent point, Q-point, bias point, etc.) of a bipolar transistor (BJT) circuit, and how the choice of the circuit design can affect how sensitive the bias point will be to the value of Beta (current gain) of the transistor. Ideally, you’d want to use a circuit which is completely independent of beta, so that a wide variety of transistor ...
