摘要：
The invention relates to a method and a corresponding system for converting a digital signal to an analog signal (50), said method using a plurality of signal sources (20), preferably current sources (56), at least two of said signal sources (20) being equal output signal magnitude sources (20), said method comprising the steps of: controlling said equal output signal magnitude sources (20) by a logic unit, providing a digital input signal to said logic unit, said digital input signal being derived from said digital signal to be converted, and summing the outputs of said equal output signal magnitude sources (20) to contribute to said analog signal (50).
