Abstract
The sampling filter apparatusincludes the first sampling switch, the second sampling switch, the first integratorfor integrating the charge input from the first sampling switch, the second integratorfor integrating the charge input from the second sampling switch, a plurality of integrators connected to both of the first integrator and the second integrator via a charging switch, respectively, the control section, a plurality of charging switches, and a plurality of discharge switches. A charge input from the sampling switch, a charge accumulated in the capacitorand a charge accumulated in a capacitorare shared by the capacitor, the capacitorand the capacitor, and the charge accumulated in the capacitoris output.
