Cascade SC Filter Opti

The optimization the cascade active switched capacitor filter is based on the solving of the bi-criteria model: maximization of dynamic - minimization of sensitivity. The criteria of dynamic maximization are defined in the way already known, i.e. maximization of dynamic is obtained by the ratio of the minimal and maximal amplitude minimization of the signal on the second-order section output. The criterion of the sensitivity is based on the average sensitivity of the section. To compute the average sensitivity a Monte Carlo technique has been applied. The proposed approximately procedure of optimization enables the effective solution of the problem. All the proceedings have been shown by application on the suitable example, and results are compared with the “exact” ones.
