CURRENT MIRROR ARRANGEMENT |
摘要 |
A current mirror arrangement is described, comprising: 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, and a current splitting circuit for deriving a part of a current from the first circuit point in the output terminal. To obtain an exact current mirror ratio which is larger than 1 between the input current path and the output current path, using a small number of components and low power supply voltages, the current mirror arrangement according to the invention is characterized in that: n is larger than 1; 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 in a ratio of m:1, in which the relation m = 1/(n-1) is at least substantially satisfied for m.
