Challenge Problems
Push your limits with challenges.
Question 1
You have a common base amplifier with a known input voltage of 5V. If the gain with C_B connected is 108, what is the expected output voltage if C_B is disconnected?
💡 Hint: Consider the effect of voltage gain when changing configuration.
Question 2
Design an equivalent circuit of a common base amplifier that minimizes loss without using C_B, describing your rationale.
💡 Hint: Think about alternative methods of directing and managing signal flow.
