2. Analysis of switched-capacitor circuits
The analysis methods are based on the fact that an ideal switched-capacitor circuit only performs instantaneous charge transfers at the moments of clock transitions. The charges transferred depend only on the potentials at the nodes at these times. It is therefore natural to associate discrete signals with these transferred voltages and charges. For example, in the circuit shown in figure 1 , the charge transferred at times t 1 depends only on the values of V e and V s at times t 2 ...

A number of analysis software packages are available, based on the principles of nodal analysis, to which refinements have been added to reduce calculation times and introduce the imperfections of active elements. Comparative analyses are available at
Examples of catalogued tours
Several manufacturers offer switched-capacitor biquadratic cells in the form of cataloged circuits. The best-known are the MF10 and LMF100 (National Semiconductor), containing two second-order biquadratic cells in a 20-pin package (DIP package) ...
