Challenge Problems
Push your limits with advanced challenges
You are designing a BJT amplifier that has to maintain high gain across a range of audio frequencies. If you were to select capacitor values to achieve the desired frequency response, how would you approach it?
💡 Hint: Look at how changes to C_E, C_C1, and C_C2 will impact performance.
If the lower cutoff frequency of a given amplifier is too high due to small coupling capacitor values, how would you modify the circuit to bring it back down?
💡 Hint: Consider how reactance changes with capacitance at lower frequencies.
