Abstract
An A/D conversion apparatus includes first to M-th ADC connected in parallel converting an analog input signal to digital signals in response to M-phase sampling signals, a reference A/D conversion circuit that converts the analog input signal to a digital signal in response to a divided-by-(n×M+1) sampling signal; and a control unit that compares, for each period of (n×M+1) clock cycles, one of the digital signals from a corresponding one of first to M-th ADC with the digital signal from the reference ADC in a predetermined order of the first to M-th ADC, and generates a compensation control signal based on the comparison result for supply to the corresponding ADC.
