57	Abstract	AB	Diese Erfindung offenbart ein Verfahren und eine sich darauf beziehende Vorrichtung zum Kompensieren einer Verstärkungs-Fehlanpassung zwischen einem ersten Digital/Analog-Wandler (410) und einem zweiten Digital/Analog-Wandler (420). Der zweite Digital/Analog-Wandler (420) ist mit einem Verstärkungsverstärker (430) verbunden. Das Verfahren umfasst die folgenden Schritte: Bestimmen eines zu dem ersten Digital/Analog-Wandler (410) korrespondierenden ersten Verstärkungswerts, Steuern des Verstärkungsverstärkers (430) mit einem ersten Steuerwert und Bestimmen eines zu dem zweiten Digital/Analog-Wandler (420) und dem Verstärkungsverstärker (430) korrespondierenden zweiten Verstärkungswerts, Steuern des Verstärkungsverstärkers (430) mit einem zweiten Steuerwert und Bestimmen eines zu dem zweiten Digital/Analog-Wandler (420) und dem Verstärkungsverstärker (430) korrespondierenden dritten Verstärkungswerts, Bestimmen eines Kalibrierungssteuerwerts entsprechend des ersten, des zweiten und des dritten Verstärkungswerts und des ersten und des zweiten Steuerwerts, ohne einen vorbestimmten charakteristischen Parameter zu verwenden, Steuern des Verstärkungsverstärkers (430) mit dem Kalibrierungssteuerwert, um die Verstärkungs-Fehlanpassung zwischen dem ersten Digital/Analog-Wandler (410) und dem zweiten Digital/Analog-Wandler (420) zu kompensieren.
