Abstract
A sensing circuit includes: a current source that outputs a direct current; an integrator that integrates a sensing current and the direct current, which is higher than the sensing current, to output an integrated value composed of the sum of a sensing voltage and a direct current voltage; and a subtractor that takes the sensing voltage from the integrated value outputted from the integrator, but not the direct current voltage.
