ABSTRACT:
Measurement amplification methods and devices for detecting a monopolar input signal (UE) by integrating A/D conversion. Before being digitized, the input signal (UE) is inverted according to the so-called Chopper principle and converted into a bipolar intermediate signal (UZ). A reference voltage (Uref) used in A/D conversion undergoes polarity changes synchronized with the polarity changes of the intermediate signal (UZ). Offset and drift are eliminated by totaling an even number of individual measurements.
