A current converter has a first amplification device, which outputs a differential current depending on a differential control signal and derives a differential feedback signal from the differential current. The current converter also has a second amplification device, which amplifies a differential input signal at its input depending on the differential feedback signal to form the differential control signal. The current converter may be used in a frequency mixer together with a mixer cell which produces a differential output signal by multiplying the differential current and an oscillator signal.
