Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

In a fixed bias circuit, if B2 varies from 100 to 200, calculate how much the collector current changes given an initial I_B of 1mA.

💡 Hint: Keep track of how B2 directly affects I_C.

Challenge 2 Hard

Design an optimal self-bias circuit that minimizes the impact of B2 variations in collector current. Explain your choice of resistors.

💡 Hint: Use R_E wisely, as it’s key to ensuring stability!
