  • Publication number: 20250047292
    Abstract: The present disclosure discloses a digital-to-analog conversion apparatus having a signal calibration mechanism. A conversion circuit performs digital-to-analog conversion on a digital signal to generate an output analog signal. An echo transmission circuit performs down-sampling on an echo path that the output analog signal passes through to generate an echo signal. Selected data and non-selected data included in N input parts of the input digital signal are treated as a pseudo-noise input and a signal input by N calibration circuits in an echo calibration circuit so as to be mapped by codeword offset tables and processed by groups of response coefficients to generate N calibration parts of a calibration signal. A calibration parameter calculation circuit generates offsets according to the echo signal, converges the response coefficients according to an error signal and pseudo noise transmission path information and updates the codeword offset tables accordingly.
