Abstract
A signal processing system including a DAC, a comparing unit, and a control unit is provided. The DAC receives a digital input and generates an output voltage. The comparing unit receives the output voltage and compares the output voltage with a reference voltage to output an output value. The control unit receives the output value and accordingly generates the digital input in a manner of value mapping through firmware or software to calibrate the DAC. Furthermore, a self-calibration digital-to-analog converting method is also provided.
