A multi-current-source comprises a voltage converter (VC), a first current source (CS1) with a first terminal (A1) which is adapted to be coupled to an output (OUT) of a voltage converter (VC) and with a second terminal (B1) which is adapted to be coupled to an input (IN) of the voltage converter (VC), at least a second current source (CS2) with a first terminal (A2) which is adapted to be coupled to the output (OUT) of the voltage converter (VC) and with a second terminal (B2) which is adapted to be coupled to the input (IN) of the voltage converter (VC), wherein the first current source (CS1) being adapted to provide a first load current (Il1) at its first terminal (A1) the first load current (Il1) being regulated to a first constant value and to provide a first unidirectional error current (Ierr1) at its second terminal (B1), wherein the at least one second current source (CS2) being adapted to provide a second load current (Il2) at its first terminal (A2), the second load current (Il2) being regulated to a second constant value and to provide a second unidirectional error current (Ierr2) at its second terminal (B2), such that a sum of the first unidirectional error current (Ierr1) and the second unidirectional error current (Ierr2) adjusts the first and the second load current (Il1, Il2).
