Abstract
A device including a first input for receiving an input current, a second input for receiving a reference current, and a first output. The device is designed to compare the input current with the reference current and, on the basis of the comparison, to output an output current.
Claims17
A device, comprising:
- a first input configured to receive an input current;
- a second input configured to receive a reference current;
- and
- a first output;
- wherein the device is configured to compare the input current with the reference current, and, based on the comparison, to output an output current at the first output;
- wherein the device is configured to ascertain whether the input current is less than a predeterminable integer n-fold of the reference current, and, based on the input current being less than the predeterminable integer n-fold of the reference current, to output the output current as a current which corresponds to an nth of the input current.
