DAC DC offset calibration method and related apparatus
The present invention discloses a DAC DC offset calibration method and related apparatus. The disclosed method includes the following steps. First, apply a first value and a second value to the DAC to generate a first measurement value and a second measurement value respectively. Then, without using any predetermined parameter, determine a DC compensation value according to the first value, the second value, the first measurement value, and the second measurement value. The DC compensation value is used to calibrate the DAC.
