Transistor biasing II
Voltage Divider Bias
The most famous circuit based on -the prototype of emitter bias is called the voltage divider bias (VDB).
Recall the steps of analyzing the emitter bias circuit:
Problem: Sometimes the voltage from the VCC power supply is too large to apply directly at the base.
- extra power supply for the base
The voltage drop across R2 is applied directly to the base, which means:
V2 = VB
1. step: find voltage drop across R2
