Dear All,
In the analysis of a two stage amplifier, we simply multiply the small signal gain of the first stage with the small signal gain of the second stage. Since the output signal from the first stage is already ampified, the input to the second stage is no longer a small signal, in such a case how can we simple assume the total gain as the product of the two small signal gains?
Thanks a lot in advance!!
Best Regards,
M.
