Abstract
Two third-order RC-active filter sections with finite transmission zeros, derived from two commonly used single-amplifier biquads, are examined, and a simple iterative procedure for their design is described, which preserves the low-sensitivity performances of the embedded biquads. Next, the third-order notch section proposed by Boctor (1975) is considered and a criterion for its low-sensitivity design is given. Finally, the above-mentioned sections together with that recently proposed by Rollett (1983) are compared from a sensitivity point of view.
