Abstract
A current mirror arrangement comprising two transistors () which are of different conductivity types and are each suitable for outputting a bias current (PBIAS, NBIAS) is specified. A controlled current source () is connected between the two transistors () and forms the output of a current mirror (). The proposed principle ensures that the output bias signals (PBIAS, NBIAS) match one another in a highly precise manner. The proposed current mirror arrangement may preferably be integrated using CMOS circuit technology.
