Challenge Problems

Push your limits with challenges.

Question 1

A BJT circuit has a collector current of 5mA and a β of 250. How would you expect the output conductance to behave if the collector-emitter voltage is increased? Provide the explanation as well!

💡 Hint: Reflect on how voltage can alter current pathways in BJTs.

Question 2

Given a BJT circuit with defined values, illustrate how you would derive the small signal voltage gain formula considering g_m, R_C, and load resistances in your approach.

💡 Hint: Use relationships derived in class and apply them to the new components.
