ABSTRACT:
An A/D converter apparatus comprising a negative feedback loop having a main signal line supplied with an input signal of a predetermined frequency and a feedback signal line passing through a feedback signal, a A/D converter connected to the main signal line for frequency-converting the input signal to a signal having a frequency different from that of the input signal to output a converted signal, a D/A converter connected to the feedback signal line for frequency-converting the feedback signal to a signal having a frequency substantially equal to that of the input signal, and a subtracter for subtracting the feedback signal from the D/A converter from the input signal to supply a subtraction result signal to the A/D converter.
