Re: I HAVE A QUESTION

Amplifiers are cascaded when the output of the first is the input to the second.
The total gain is the product of the cascaded amplifier stages.

Re: I HAVE A QUESTION

Cascode = a single amplifier (which might have many number of transistors for gain boosting purpose)

Cascade = you add up a few stage of single amplifier (like adding block in series)
 

I HAVE A QUESTION

haiiiiiiii
just now i saw ur quoestion.
i am sorry for not replying u these many days.
i was not knowing tht i have to open in tht way on clicking all posts for quoestions.
i joined very recently.
the answer for ur quoestion is
ok i think u know cascading.
do u know push pull amplifier ckts.
there also the pnp transistors collector terminal will be connected to emiter of npn transistor.
ok
this is cascoding
i think most of the ckts terminals are cascoded
and the ckts are cascaded.
ok
 

Re: I HAVE A QUESTION

they are absolutely different!

you must make sensitive to the terms.

cascade - serial connection cascode - common source and common gate
