current feedback amplifier (CFA)

As can be seen from the name CurrentFeedback Amplifier (CFA), in a Current Feedback Operational Amplifier (CF-OpAmp) current is fed back from the lowest possible impedance amplifier output to an inverted low impedance amplifier input. The advantages of this feedback technique are the high bandwidth and a gain that is relatively constant over the bandwidth.
