摘要： A high order integrator is configured using an operational amplifier, a first filter connected between an input terminal of the integrator and an inverted input terminal of the operational amplifier, and a second filter connected between the inverted input terminal and output terminal of the operational amplifier. The first filter includes n serially-connected first resistance elements, n-1 first capacitance elements each connected between each interconnecting node of the first resistance elements and the ground, and n-1 second resistance elements each connected between each interconnecting node of the first resistance elements and the ground. The second filter includes n serially-connected second capacitance elements, n-1 third resistance elements each connected between each interconnecting node of the second capacitance elements and the ground, and n-1 third capacitance elements each connected between each interconnecting node of the second capacitance elements and the ground.

摘要： PROBLEM TO BE SOLVED: To reduce occurrences of a power source voltage fluctuation and unnecessary radiation accompanying potential movement at the time of charging or discharging a sampling capacitor, and to perform precise sampling operation.
SOLUTION: When a transistor switch for controlling the charge timing of the sampling capacitor is serially connected to a transistor switch for controlling charge speed, a transition duration when a transistor for controlling charge speed changes from an off-state to a complete on-state is made longer than a transition duration when the transistor switch for controlling the charge timing changes from the off-state to the complete on-state. On the other hand, when a transistor switch for controlling the discharge timing of the sampling capacitor is serially connected to a transistor switch for controlling discharge speed, a transition duration when a transistor for controlling discharge speed changes from the off-state to the complete on-state is made longer than a transition duration when the transistor switch for controlling discharge timing changes from the off-state into the complete on-state.

摘要： PROBLEM TO BE SOLVED: To reduce the energy consumption by setting one input terminal of an active element to a potential independent of an input signal during the time of first and second stages. SOLUTION: An integration capacitor Co is fixedly connected with the drain of an active element Mts which receives a constant current bias. An input terminal 122 of a sampling transistor Mss is fixedly connected with an input signal Us and sampling of input signals between two clock steps is performed. The input signal is sampled on the first clock step, inputted through a switch S1 to a capacitor Ci1 and next, the input signal is sampled during the second clock step and inputted through a switch S2 to a capacitor Ci2. During this term, one input terminal of the active element Mts and one input terminal of the integration capacitor Co are held at the potential independent of the input signal.
