Generally, the gain of a transistor amplifier falls at high frequencies due to the___________?
Correct answer: A. Internal Capacitance of the device
- A. Internal Capacitance of the device
- B. Coupling capacitor at the input
- C. Skin effect
- D. Coupling capacitor at the output
Explanation
At high frequencies, the transistor's internal junction and stray capacitances provide low-reactance paths that reduce gain. Coupling capacitors mainly affect the low-frequency response, while skin effect is not the principal cause here.
