Abstract (en)
[origin: WO2009074386A1] Signal modulator for analog/digital converter comprising: a first modulator stage having an input for the analog input signal, a comparator (U1) configured to compare the output signal of the first modulator stage to a voltage value (P1), a quantizer (D1) configured to generate a series of digital signals by scanning the output signal of the comparator (U1) with a scanning frequency, and a feedback loop, which feeds the output signal of the quantizer back to the first modulator step, wherein it is provided according to the invention that the first modulator stage is formed by at least one RC member (R1C1), and the feedback loop connects the output of the quantizer (D1) to the output of the at least one RC member (R1C1).
