Calculate the voltage gain, input resistance, output resistance for a common base and common collector transistor configuration using the hybrid pi model.

I searched like hell for the soltutions of these two..............i will be highly obliged and even be willing to donate points if you provide me the soltution..............

thanks in advance...............

Not sure if this is exactly what you asked but Grey and Meyer has a complete analysis of those configurations..

For common Base
Av = gmRc
Rin = 1/gm
Rout = ro//Rc

thanks for the reply but i wanted a detailed derivation ..........can u refer to some online links to the books or websites or provide me the soulution ...........
thanks in advance.........

Here you have a simple solution with Ro-->infinity. If Ro is not infinity, you have to calculate all this, the same way, with some more equations.

Thanks a lot mate......you have been very supportive indeed......can u explain me one other thing ? what's the difference between Ro-->infinity and Ro not being infinity.... what are the advantages and disadvantages associated with them.........? i am trying to solve the problem with Ro not being infinity......if I have any problems i will post again.........? will that be a problem to you......?

thanks in advance........
