| Abstract: | This paper gives a systematic and general analysis method to take into
account the effect of the finite gain-bandwidth product(GB)of the opera-
tional amplifiers on the response of switched-capacitor filters(SCF).This
approach is easy to im plement on the computer and is particularly suitable
to solve higher-order SCF circuits.Finally,the responses of two bandpass
filters with same ideral transfer function but different configurations are
given as illustrative examples. |
