Abstract
An integrator includes a first switch, a first capacitor, a second switch, a second capacitor, an amplifier, a third switch, a forth switch, a third capacitor, and a control circuit. The control circuit repeats a first phase and a second phase. In the first phase, the control circuit renders the first switch and the third switch to turn on and the second switch and the fourth switch to turn off. In the second phase, the control circuit renders the second switch and the fourth switch to turn on and the first switch and the third switch to turn off.
