Analysis of switched-capacitor circuits
Filtres à capacités commutées

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 t₁ depends only on the values of V_e and V_s at times t₂ = (2n - 1)τ :
