Semiconducting Devices Question 265

Question: In a triode, gm=2×103ohm1;μ=42 , resistance load, R=50 kilo ohm. The voltage amplification obtained from this triode will be

[MNR 1999]

Options:

A) 30.42

B) 29.57

C) 28.18

D) 27.15

Show Answer

Answer:

Correct Answer: B

Solution:

Voltage gain Av=μ1+rpRL and μ=rp×gm

Therefore rp=422×103=21000Ω

Therefore Av=421+2100050×103=29.57
