Abstract
The present invention provides a composite circuit with analog to digital conversion (ADC) and digital to analog conversion (DAC), with which the quantization curves of ADC and DAC are obtained by the same digitization circuit, and integrated in one chip to eliminate nonlinear and linear error (hereinafter referring as error in general), and low-distortion restoring signal. The present invention is able to perform self error-correction in the signal restoring stage, and thus the error caused by the digitization circuit can be eliminated. Therefore, the present invention provides a composite circuit with ADC and DAC, which not only reduces the size of integrated circuit but also obtains more accurate signals and increases the overall operating efficiency.
