In this video, the Emitter Stabilized Biasing and Emitter Biasing Configuration of the BJT is explained in detail.
By watching this video, you will learn the following topics:
0:00 Introduction
0:21 Fixed Bias with Emitter Resistor (Emitter Stabilized Bias)
4:19 Variation in operating point with the change in current gain (β)
8:10 Condition for the stable operating point in Emitter Stabilized Bias Configuration
10:48 Emitter Bias Configuration (DC Analysis)
13:33 Condition for the stable operating point in Emitter Bias Configuration
Emitter Stabilized Bias Configuration:
It is the Fixed bias Configuration with the emitter resistor. The resistor at the emitter terminal provides negative feedback and tries to stabilize the operating point against the variation in current gain (β)
Emitter Bias Configuration (Two Supply Emitter Bias):
In this configuration, the biasing voltage is applied at the emitter terminal through the feedback resistor.
To get a stable operating point and a very small base voltage, the base resistance should be very small.
