ABSTRACT:
An oversampling analog/digital converter includes a given number of at least three identically constructed switched-capacitor converter stages each being triggered by an analog input signal and each outputting both an analog and a digital output signal. The converter stages are connected in series with respect to the analog input and output signals. The given number of series-connected differentiation stages are each connected downstream of a respective one of the converter stages for receiving and adding the digital output signals of the converter stages.
