I tried to cascade two circuit consisting of BJT transistor : Common Emitter stage, Emitter follower.
I do abstraction like belows, which means you just need to know only each unit block one by one and when you cascading these blocks, then whole system does sort of cooperating all blocks's function (like LEGO blocks, it might also called 'decomposition' or something).
As you know, each circuit has
I want to know what relations each properties have when cascaded.
For example, I can guess that
(Av_total) = (Av1) * (Av2).
But, what about
Rout_total ? Are they related with
Rin, Rout of each block, saying parallel connection of each
Rin or something?
