Topic: Analog Electronics
Reason for superior high frequency performance of metal-semiconductor diode compared to p-n junction diode is:
- A. Higher conductivity of metal compared to semiconductor
- B. No minority carrier storage effect in metal-semiconductor diode
- C. Metal semiconductor junction does not rectify RF signal
- D. Hole is the majority carrier in Schottky barrier diode operation
Answer: B. No minority carrier storage effect in metal-semiconductor diode
Explanation: Metal semiconductor diodes do not have minority carriers, so reverse recovery time is less. Thus they can be used for switching at high frequencies.
