Abstract (en)

[origin: WO2006024525A1] The invention relates to a current mirror arrangement wherein two current mirror transistors (2, 3) form a current mirror. Two cascade transistors (11, 12) are interconnected with the two current mirror transistors (2, 3), forming a cascade stage. Said cascade transistors (11, 12) respectively comprise a plurality of partial transistors (13, 14, 15; 16, 17, 18) that are interconnected in series in terms of the controlled sections thereof. In this way, the connection nodes of the current mirror transistors can be connected to a connection node between two partial transistors (14, 15). This, in turn, causes an enlargement of the input voltage range for a current source (4) that supplies an input current for the current mirror.
