Abstract

PURPOSE:To eliminate spikes generated when integrations are started, by supplying an electric current which has the same intensity as, and antiphase to the signal current, to the output terminal. CONSTITUTION:When the output of a gate multivibrator 2 is at a high electric potential, both a gate diode 3 and a clamp diode 4 are set to ON and a Miller integrator 5 is set to the waiting condition. When the output of the gate multivibrator 2 becmes low in electric potential under this condition, the Miller integrator 5 produces a negative spike at the output terminal of an inversional amplifier 6 at the time when an integration is started. At this time, an antiphase generator 11 outputs an electric current which has the same intensity, and antiphase to the electric current flowing through the gate diode 3, and supplies the electric current to the output terminal of the inversional amplifier 6 as a spike current of the normal direction after the electric current is differentiated at a resistance and a condenser for compensation 13. Therefore, when the size of this normal spike is equal to the negative spike and when there is no lag in the phase of both spikes, both spikes are compensated by each other.
