A direct compensation method is introduced to reduce the quantization distortion and non-linearity error of A / D conversion. This method can reduce the nonlinear distortion when the noise of analog signal increases, and the computer simulation and experimental test results are given. The method is particularly suitable for reducing higher harmonics and improving A / D conversion results.
