Abstract
Devices and methods for calibration of amplifier stages and for compensation of errors in components connected upstream of amplifier stagesThe described amplifier stage calibration comprises the following steps: creation of appropriate conditions for calibration of the amplifier stage, comparison of signals which are output by the amplifier stage or electrical quantities which occur within the amplifier stage with each other or with assigned reference values, and changing those properties of the amplifier stage which are to be calibrated depending on the result of the comparison. The described compensation of errors in components connected upstream of amplifier stages takes place through a corresponding calibration of the amplifier stage. Through the described devices and described methods, the calibration of amplifier stages and the compensation of errors in components connected upstream of amplifier stages can be carried out in an amazingly simple way, quickly and precisely.
