Impedance makes the feedback network operate in current source mode. The current feedback operational amplifier is a type of electronic amplifier whose inverting input is sensitive to current rather than to voltage as in a conventional voltage feedback operational amplifier. Current feedback op amps are often called transimpedance op amps because the open loop transfer function is an impedance.

During normal operation the input voltage vidrives a current ip into. A current feedback op amp responds to an error current at one of its input terminals rather than an error voltage and produces a corresponding output voltage. 2 for a combination of voltages or currents at the input the input resistance goes high or low. A current feedback op amp circuit collection 7 5 summary current feedback op amps can be successfully used in a variety of applications.
