摘要： An adding circuit includes storage capacitors and a a switch mechanism, the storage capacitors being charged up via voltage signals to be added during a first clock phase. During a second clock phase, the storage capacitors are connected in parallel, with the result that a charge equalization occurs. After the charge equalization, the voltage dropped across the parallel-connected storage capacitors is equal to a sum of the signals to be added except for a scaling factor. In one embodiment, the adding circuit is used in a sigma-delta modulator circuit.

摘要： An analog-to-digital converter system converts an analog input signal into a digital output signal. The analog input signal is converted into a first digital signal by a fed back analog-to-digital conversion. A second digital signal is additionally formed, depending on the analog input signal or on the digital output signal, which, combined with the first digital signal, results in the digital output signal.
