The disclosure relates to an active balun (300), including: a first terminal (303); a second terminal (305, 306); a first transistor (M1) comprising a first current path (D1-S1, l DS ) and a control path (G1-S1, V GS ) for controlling the first current path (D1-S1, l DS ), wherein the first current path (D1-S1, l DS ) is coupled between the first terminal (303) and the second terminal (305, 306) and the control path (G1-S1, V GS ) is coupled between a reference potential (304b, G1) and the first terminal (303, S1); and an inverter (301) comprising a second current path (S2-D2-D3-S3), wherein the second current path (S2-D2-D3-S3) is coupled in parallel to the first current path (D1-S1) of the first transistor (M1).
