Challenge Problems
Push your limits with challenges.
Question 1
Design a BJT differential amplifier with specified resistor values and input conditions. Explain the reasoning behind your choices.
💡 Hint: Think about what resistor values would stabilize your amplifier’s operation.
Question 2
You have an Op-Amp with a gain of 15 and a typical bandwidth of 200 kHz. Calculate the gain-bandwidth product and predict the new bandwidth if the gain were lowered to 5.
💡 Hint: Remember GBW is constant—both gain and bandwidth are inversely related.
