ARRANGEMENT FOR READING OUT AN ANALOG VOLTAGE SIGNAL

摘要

An arrangement for reading out an analog voltage signal includes a voltage signal input for applying the analog voltage signal thereto, a reference unit configured to generate an analog reference voltage, and a converting unit configured to convert an analog input signal into a digital output signal. To enable online self-calibration of the arrangement, the arrangement includes a superposition unit configured to receive the analog voltage signal and the analog reference voltage. The superposition unit includes a modulation unit configured to generate a modulated reference voltage from the analog reference voltage. The superposition unit is configured to generate a combined analog signal by superimposing the modulated reference voltage onto the analog voltage signal, and to forward the combined analog signal to the converting unit.
