Abstract

The authors answer the comments raised by P. V. Ananda Mohan about their paper on active -RC ﬁlters, and explain the differ- ences of the ﬁlter structure reported in their paper with respect to the in- dicated examples from literature. The results of the analysis of the effect of the opamp second pole are also discussed.
