Question

High cutoff frequency can be found in....which of the following....??
a. common base
b. common collector
c. common emitter

Answer 1

sri we didn't study about frequency in electronic 2 we will learn about it in electronic 3
but i will check my books . may be i find s.th for u

Answer 2

ok try try

Answer 3

dear as i know cut off frequency almost use for ap-amp
and we know that gain has inverse relative with b-w

Answer 4

i'll meet my electronic professor tomorrow , i 'll ask him and i will answer u tomorrow night .

Answer 5

i hope u could wait till tomorrow .

Answer 6

yeah sure i can wait

Answer 7

but i think common base has the width because it has least gain , and i know cut off frequency is depend on resistor and their design .
if u learnt about f 3db u would know its cut off frequency / sqrt 2
and f l 3db = 1/ C Req
do you know about this formula ?

Answer 8

as this formula said the frequency is not depend on the transistor design but to be sure i will ask tomorrow .

Answer 9

i am not getting exactly u can discuss ur professor then after we will get it i think meanwhile i am going to check my books

Answer 10

check frequency response chapter i would be useful .

Answer 11

ok

Answer 12

i am not able to get answer from book when u discuss it with ur professor let me know

Answer 13

i'll do

Answer 14

ok

Answer 15

did u get answer to my question....?
