In this paper we introduce a new design procedure for low-sensitivity filter sections, which have a symmetrical passive-RC network in the operational amplifier (opamp) feedback loop. In the design procedure we apply impedance scaling to the symmetrical bridged-T and twin-T networks; they become "potentially symmetrical" (G.S. Moschytz, Linear integrated networks: fundamentals, V. Nostrand Reinhold, 1974). The design of low-sensitivity all-pole active-RC filters, which have an RC-ladder network… CONTINUE READING
