Abstract
A multi-current-source comprises a voltage converter (VC), a first current source (CS) with a first terminal (A) which is adapted to be coupled to an output (OUT) of a voltage converter (VC) and with a second terminal (B) which is adapted to be coupled to an input (IN) of the voltage converter (VC), at least a second current source (CS) with a first terminal (A) which is adapted to be coupled to the output (OUT) of the voltage converter (VC) and with a second terminal (B) which is adapted to be coupled to the input (IN) of the voltage converter (VC), wherein the first current source (CS) being adapted to provide a first load current (Il) at its first terminal (A) the first load current (Il) being regulated to a first constant value and to provide a first unidirectional error current (Ierr) at its second terminal (B), wherein the at least one second current source (CS) being adapted to provide a second load current (Il) at its first terminal (A), the second load current (Il) being regulated to a second constant value and to provide a second unidirectional error current (Ierr) at its second terminal (B), such that a sum of the first unidirectional error current (Ierr) and the second unidirectional error current (Ierr) adjusts the first and the second load current (Il, Il).
