A systematic method of state-space synthesis for SCFs with low-sensitivity

The authors present a systematic state-space synthesis method for designing practical precision switched capacitor filters (SCFs) with low-sensitivity to component variations in the passband. A general form of the matrix set of the state equations (matrix representation of the state equations) and the relationship between the matrix set and the voltage transfer functions are given for the SCFs with low-sensitivity performance. The results show that it is very simple to design low-sensitivity SCFs by the method presented
