Abstract :
Realisation of a switched-capacitor filter circuit with decimation of the input sampling frequency is proposed. The circuit, which is compensated for the influence of parasitic capacitances, is useful as an input stage of an SC filter. It can also be used for the realisation of an integrator, based on Simpson´s rule.
