Challenge Problems

Push your limits with challenges.

Question 1

Design a multi-stage amplifier using both CE and CC configurations. Calculate the total voltage gain if individual gains are 20 and 10.

💡 Hint: Remember that gains multiply when stages are cascaded.

Question 2

If a composite transistor has one stage configured as CE with r_pi=200 Ohm and β=150, and another as CC with negligible output resistance, calculate the increase in input impedance.

💡 Hint: Refer to input impedance formulas of cascaded configurations.
