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 Q and pole frequency \\omega _0 , the circular root locus centered at -2Q \\omega _0 on the real axis and of radius \\omega _{0}\\sqrt {4Q^{2}-1} exhibits zero Q -sensitivity and zero gain-sensitivity product (GSP) with respect to the active parameter. Furthermore, realization techniques to achieve zero Q -sensitivity and zero GSP for prescribed Q and \\omega _0 are outlined. Experimental results agree closely with the theoretical expectations.
