Challenge Problems
Push your limits with advanced challenges
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.
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.
