A rigorous and general derivation of the modified nodal equations needed for a time, frequency and

-domain analysis of multiphase switched-capacitor networks is given. Also a general equivalent circuit for switched-capacitor networks is derived. This technique allows to handle continuous coupling, piecewise-constant inputs as well as continuous inputs. These results can be used to adapt existing circuit analysis programs, based on modified nodal analysis, for efficient simulation of switched-capacitor networks.
