ABSTRACT:
A current feedback circuit for controlling the error current in current feedback amplifier includes transistor biasing circuitry which monitors the error current to detect high input signal slew rates and switches on a transistor controlled shunt circuit to divert drive current from the transistors forming the amplifier input, when the error current generated exceeds a threshold value.
