Current mirror arrangement
摘要:
A current mirror arrangement including an input current path comprising a main current path of a first current mirror transistor and a transistor connected thereto in a cascode configuration and referred to as first cascode transistor, an output current path comprising a main current path of a second current mirror transistor and a transistor connected thereto in a cascode configuration and referred to as second cascode transistor, the current mirror transistors being interconnected in a current mirror configuration and their control terminals being connected to a first circuit point, the connected control terminals of the cascode transistors being interconnected and being connected to an input terminal in the input current path of the current mirror arrangement, the input terminal being constituted by a terminal of the main current path of the first cascode transistor, and an output terminal being constituted by a terminal of the main current path of the second cascode transistor, and a current splitting circuit for deriving a part of a current from the first circuit point in the output terminal, the current splitting circuit is adapted to split up the current from the first circuit point directly to the output terminal and a reference point.
