A charge-pump circuit arrangement with input side, output side and two current balancing circuits (current mirrors), which form a source-branch for generating a source current and a sink- branch for sinking current. The two branches each have at least one input-side transistor (mn3,mp3) an output-side transistor (mn1,mn1), two output-side transistors (mn2,mp2) and an input- side symmetry transistor (mn4,mp4; mn41,mp42). At least one of the input-side symmetry transistors is assigned a second transistor (mp42,mn42) for improving the symmetry between the source-branch and the sink-branch.
