Challenge Problems
Push your limits with advanced challenges
Calculate the overall gain of two cascaded CE amplifiers with gains of 15 and 3. Assume the loading effect reduces the total gain by 20%.
💡 Hint: Multiply the individual gains first, then apply the reduction.
Describe the effects of adding a buffer with high input resistance but significant output capacitance between two CE amplifiers.
💡 Hint: Consider how the capacitive loading interacts with the resistances in the circuit.
