10:25 Solved Example

The collector feedback Bias

In Collector Feedback Bias, the circuit tries to stabilize the operating point through the negative feedback. In this configuration, the feedback resistor is connected between the collector and the base resistor.

Although this configuration provides better stability than Fixed Bias Configuration, still the operating point may shift with the change in the external parameters.

To improve the stability and increase the negative feedback, the emitter resistor can be included.

Collector Feedback Bias with Emitter Resistor (Collector-Emitter Feedback Bias) :

To improve the stability, and increase the negative feedback, the emitter resistor can be included in the circuit.

In this video, the DC analysis of Collector Feedback Bias and Collector-Emitter Feedback Bias is explained and at the later part of the video, the example has been solved based on this configuration.
