Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a Voltage Divider Bias circuit for a BJT, given VCC = 12V, target IC = 3mA, and VCE = 6V. Specify RE, RC, R1, and R2 values.

💡 Hint: Start with VE before calculating RC and then carefully determine R1 and R2.

Challenge 2 Hard

Evaluate the Q-point stability of the designed Voltage Divider Bias circuit when the temperature increases. Calculate the expected changes in IC and VCE with increased beta due to temperature effects.

💡 Hint: Remember how negative feedback functions in relation to parameter variations.
