What is a cascode amplifier supposed to do???
I read it in a book that cascode changes the dc level of the input signal (say make the dc level zero) without attenuating the ac component....
On the other hnd its mentioned all over the net that it consists of CE amplifier followed by a CB stage...n is used to obtain good impedance match over a wideband...
Which is it really???
