  • Patent number: 5497155
    Abstract: An analog-to-digital convertor apparatus finds input signals of a comparison output to a virtual reference potential between reference potentials with significantly fewer elements in the comparator than in the prior art. A composite inverted output current and a composite in-phase output current are generated by adding the in-phase comparison output current of the first and second comparison output currents of an input signal to the first and second reference signals. Then, an interpolation output means compares the generated composite output currents with a comparison output current which is opposite in phase to these composite output signals. This enables the comparator circuit to obtain the result of comparison of the input signal to a virtual reference signal existing between the first and second reference signals.
