ABSTRACT:
An improved circuit for compensating an input/output characteristic linearity of a parallel comparison type analog-to-digital converter which reduces a wasteful consumption of current in the linearity compensation circuit. In the improved linearity compensation circuit, a dummy circuit having the same construction as a bias circuit of each comparator of the A/D converter is installed for providing a current I.sub.E which is an amplification of an input current by means of the input circuit of each comparator, a first current multiplier is installed for providing a multiplied current kI.sub.E on the basis of the current provided by the dummy circuit, an amplifier is installed for providing a current ki which corresponds to a multiplication of the current i by an amplification factor of the input circuit, and a second current multiplifier is installed for providing another multiplied current kli which is a multiplication of the current ki by l. The other multiplied current kl is auxiliarily supplied to the input circuit. Therefore, the wastefully consumed current can be reduced to approximately kI.sub.E.
