The design of high order switched-capacitor highpass filters is
presented. Emphasis is placed on the design procedures of cascaded
biquadratic sections and ladder network realizations of switchedcapacitor
highpass filters. The stability problem of the doubly terminated
switched-capacitor ladder highpass filter is discussed. Design
examples are presented to illustrate the design procedures. The
sensitivities of the realization methods are discussed. An .analytical
equation of the gain deviation for the cascaded biquadratic sections
realization is derived. Monte Carlo analysis is performed for the
design examples. The results of the analyses are compared to reveal
the differences in sensitivities in terms of the order of the filters
and the type of realizations.
