Abstract
An impedance measuring circuit has an amplification circuit connected to a target and to amplify a predetermined input signal with a gain corresponding to an impedance in the target and to output an output signal, a peak hold circuit to hold a peak value of the output signal and to output a hold value, and an impedance calculation circuit to calculate the impedance in the target based on the hold value.
