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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

ok try try

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

i hope u could wait till tomorrow .

OpenStudy (anonymous):

yeah sure i can wait

OpenStudy (anonymous):

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 ?

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

check frequency response chapter i would be useful .

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

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

OpenStudy (anonymous):

i'll do

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

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