Delta - sigma modulator for an analog - digital - converter with only one return coupler coefficients

摘要

it is a delta sigma modulator (or rauschformer) described the resolution of more than 18 bits level. the delta sigma modulator may increase the linearity and dimension reduce by only a ru00fcckkoppelschleifenweg used and a coefficient less than one to the integrierer sets.the delta sigma modulator of the present invention can for the analogue to digital converter with a reduction of the effective value of the capacitor can be used. in the case where the decimal values into digital values to be corrected, it is possible to design the digital rauschformer in the digital analogue converter is used.
