Anyone knows what exactly is called Gilbert cell? How many transistors does it
actually have? And does it have a tanh nonlinear response from one differential
input or is there some kind of split current mirror used to factor this
nonlinearity out and get a perfect linear analog multiplier?

Is it possible to make a well working Gilbert cell with ordinary non-matched
transistors?

And btw do you know what translinear mean?
