What is the difference between cascode amplifier configuration and cascade amplifier configuration?
From a transistor perspective, a cascade is typically when the amplifier load(s) are connected in a left-to right horizontal chain configuration, whereas a cascode has the load(s) stacked vertically.
edit. whoops, I somehow linked on an older post. Sorry if it is out of place.
In a cascade:
the output of the first amplifying device (transistor) is fed as input to the second amplifying device,
whose output is fed as input to the third,
and so on until an adequate signal amplification has been achieved.
An amplifier consisting of a common emitter input stage that drives a common base output stage.
advantages include high gain and low noise.
Go through these links you may get an clear idea about these.
