Abstract
The present invention is related to an analog/digital converter which includes a multitude of integrating circuits, a 1 bit analog/digital converter and a 1 bit digital/analog converter. The multitude of analog integrating circuits are connected in series and the 1 bit digital/analog converter is connected downstream from the last analog integrating circuit of the series. An output signal of the 1 bit analog/digital converter is transmitted to the 1 bit digital/analog converter, and an output signal of the 1 bit digital/analog converter is subtracted from an input signal of each analog integrating circuit. A multitude of input signals is transmitted via a multiplexer to the first analog integrating circuit of the series-connected analog integrating circuits. Each analog integrating circuit includes a multitude of capacitors which correspond to the multitude of input signals, whereby a capacitor of the multitude of capacitors can be switched each time between an output and an input of the analog integrating circuit. The output signal of the 1 bit digital/analog converter is delayed according to the multitude of input signals.
