A device and a method including current measurement and/or amplification is disclosed. One embodiment provides supplying a current to be measured to a current amplifier. The current is amplified by the current amplifier. The amplified current or a current generated is fed back therefrom to the current amplifier. The current amplifier may include a current mirror. Furthermore, at least one delay means may be used by which the process of current amplification and/or current feedback may be delayed correspondingly.
