Challenge Problems
Push your limits with advanced challenges
Design a BJT amplifier for a specific application requiring a mid-band gain of 50 and an input resistance of at least 50 kΩ. Given the constraints, suggest values for R_C, R_B, and an approximate biasing method.
💡 Hint: Consider using a voltage divider for biasing to maintain stability.
Explain how the performance of the amplifier would change if the bypass capacitor is omitted.
💡 Hint: Think about the role of feedback in amplifier design.
