A circuit arrangement for a comparator has first and second input terminals (20,22) and first and second output terminals (30,32), and two transistors (1,2) connected via a current source (7) to a reference potential (Vref), of which at least one gate terminal (G) is joined to the first input terminal (20). A current mirror arrangement is connected between the first and second transistors (1,2) and the output terminals (30,32). The gate terminals (G) of the first and second transistors (1,2) are connected to the first input terminal (20) and the first or second transistor (1,2) has a smaller operating voltage (Uth1,Uth2) than the second or first transistor (2,1). The latter transistors specifically being MOS-transistors.
