Formulation of the nodal equations of switched capacitor networks containing nullors

A method is given for determining the nodal equations of an ideal active switched capacitance (SC) network, containing switches, capacitors, and nullors. These equations are obtained directly by row-column operations on the passive unswitched nodal capacitance matrix. The results are extended to the P-phase case.
