Maximum value of gain if tranistor not to be saturated

Click For Summary
The discussion focuses on understanding the saturation of a transistor and its implications for calculating maximum gain. It clarifies that a transistor is considered saturated when the base voltage exceeds the collector voltage. The maximum value of gain is determined when the collector voltage is at 0.6V, leading to a collector current of 11.4 mA. The calculated gain (B) is found to be 570 based on the given parameters. This highlights the relationship between collector voltage, current, and gain in transistor operation.

I don't know how to calculate part C) of the question. I'm unsure what saturation of a transistor refers too.

If the base voltage is greater than the collector voltage, then it is saturated. The more collector current, the higher voltage drop across Rc, which lowers the collector voltage.

Ok. So the maximum value would occur when the collector voltage is 0.6V also. If that is the case:
  • The voltage across RC would be 11.4V
  • The current IC would be 11.4/1000 = 11.4 mA.
  • And with that , B would be (11.4 x 10-3)/(20 x 10-6) = 570
