摘要： A digital-to-analog converter and a performing method thereof are disclosed. The digital-to-analog converter includes a random rotation unit, a plurality of conversion units, and a summing unit. The random rotation unit receives a plurality of binary-weighted inputs and generates a plurality of rotated digital outputs according to a random rotation number. The conversion units respectively receive one of the rotated digital outputs and generate a respective analog output. The summing unit sums the respective analog outputs of the conversion units for generating an analog output. The present invention implements the dynamic element matching technique by randomly rotating the binary-weighted inputs, so as to reduce the manufacturing cost of the digital-to-analog converter.
