✦ Synopsis

A number of new elements for switched-capacitor filters based on voltage inverter switches will be described. The new circuits simulate elements which are obtained from the normally used ones by FDNR transformation. They are insensitive to bottom plate parasitics and the influence of the top plate parasitics can be reduced. N o matching is required between any capacitors in the SC circuit, so that the same low sensitivity to element variation holds as for the reference structure. These new elements allow realization of some further filter structures.
