Abstract
A leakage current correcting circuit for reducing a leakage current flowing into an output of a circuit in a high impedance state. The configuration includes a correcting unit having a current detecting circuit for detecting a leakage current and outputting a current equal to a detected leakage current, and a current supply circuit for receiving the output current from the current detecting circuit as an input and causing a current for offsetting the leakage current flowing into the output of the circuit in a high impedance state.
