Abstract
A root locus with respect to the active parameter for any second-order active RC filter is circular with center on the real axis. It is shown that for any pole pair 
and pole frequency 
, the circular root locus centered at 
on the real axis and of radius 
exhibits zero -sensitivity and zero gain-sensitivity product (GSP) with respect to the active parameter. Furthermore, realization techniques to achieve zero -sensitivity and zero GSP for prescribed and are outlined. Experimental results agree closely with the theoretical expectations.
