PURPOSE: To obtain a sampling signal integrator capable of integrating signals at twice conventional speed. CONSTITUTION: The sampling signal integrator is constituted of an amplifier 111, two pairs of capacitors 120, 130, 140, 150 and a voltage bias connected to the branches of respective input terminals of the amplifier 111 and capable of biasing the integrator to a common mode. The 1st pair of capacitors 120, 130 is connected between the input and output terminals of the amplifier 111 by a normal negative feedback form and the 2nd pair of capacitors 140, 150 is connected to the input terminal of the amplifier 111 by the 1st pair of switches 160, 170 and similarly connected to a voltage source 200 by a 2nd pair of switches 180, 190. The two pairs of switches are used for cross connection or synchronization to execute double speed integration.
