ABSTRACT:
The invention provides a method for mixing signals with an analog-to-digital converter. The analog-to-digital converter receives a plurality of analog signals. First, the plurality of analog signals are respectively converted to a plurality of first datastreams with a plurality of first delta-sigma modulators. The plurality of first datastreams are then mixed to generate at least one second datastream. The at least one second datastream is then converted to at least one third datastream with at least one second delta-sigma modulator. The at least one second delta-sigma modulator and the plurality of first delta-sigma modulators are triggered by the same clock signal.
