Abstract
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.
