An integrating network for performing integration of an input voltage by the use of an integrator comprising time-constant means and a d-c amplifier, wherein a drift memory circuit is provided between the output and input of the integrator for feeding back in the opposite polarity the output of the d-c amplifier to the input of the integrator in a case of no input of the d-c amplifier so as to obtain a stationary condition and for continuously sending out, as a feedback signal, a voltage fed back to the input of the integrator at the stationary condition, the feedback signal having a value substantially equal to the drift voltage of the d-c amplifier converted in terms of the input of the d-c amplifier, whereby an input voltage is integrated in the integrating network without error caused by the drift of the d-c amplifier.
