current feedback opamps

has any one designed a current feedback opamp.
Whyis that not much work has not be done in current feedback opamps.
please suggest some material to refer to design one such opamp

Re: current feedback opamps

thanks for the book Haoyun.
But can u clear this doubt to me.
What i am not sure is whether the inputs are voltages or currents.
THere is a matrix describing the current conveyor s operation
Vx= 0 1 0 Ix
Iy =0 0 0 Vy
Iz =1 0 0 Vz
So which are the input ports X,Y or Z. ?

Re: current feedback opamps

Current amplifiers and current feedback amplifiers are distinct.
As I understand you mean current feedback opamp, like the one from here **broken link removed**
Am I right?

Re: current feedback opamps

So you can find some info in the book Palumbo G., Pennisi S. Feedback Amplifier, 2003.

Maybe this paper will be helpfull for you also.
