The design procedure of low-sensitivity second-and third-order class-4 Sallen and Key active resistance-capacitance (RC) allpole filters, using impedance tapering, has already been published. There a ladder structure in the positive feedback loop of an operational amplifier was used. In this paper desensitization using impedance tapering is applied to(More)
In this paper a method of realizing seventh-order elliptic filter using signal-flow graphs is presented. The elliptic filter having a minimum number of capacitors is compared with the filter having a higher number of capacitors. The version with minimum number of capacitors provides area savings in IC form. Both filters (i.e. filter with minimum and one(More)
The design procedure of low-sensitivity, low-pass (LP) 2-and 3-order class-4 Sallen and Key active resistance-capacitance (RC) allpole filters, using impedance tapering, has already been published [1]. In this paper desensitization using impedance tapering is applied to HP and BP 2-order filters. It is shown that HP filters have dual properties to LP(More)
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" [1]. The design of low-sensitivity(More)
In this paper we present an optimal design procedure for secondand third-order active resistance-capacitance (RC) single-amplifier building blocks that are used to build a high-order tolerance-insensitive allpole filter. The design procedure of low-sensitivity, low-pass secondand third-order active-RC allpole filters, with positive feedback, has already(More)
One of the problems with on-chip active-RC filters is that in order to satisfy tight specifications accurately, they need to be fine-tuned. This becomes more difficult with increasing filter order. In this paper, we introduce a simplified tuning method which is obtained by a new structure consisting of a filter section of second- or third-order (Biquad or(More)
In this paper a method of realizing elliptic filters using signal-flow graphs is presented. Elliptic filters having a minimum number of capacitors are compared with those having a higher number of capacitors. This number is particularly significant when comparing filters realized in balanced-toground and unbalanced form. The version with a canonic number of(More)
In this paper it is shown that active-RC filters can be designed to have low-sensitivity to passive components and at the same time possess low output thermal noise. The design procedure of low-noise and low-sensitivity, positive-feedback, secondand third-order low-pass allpole filters, using impedance tapering, has already been published. The noise(More)
This paper presents the low-sensitivity realization of narrow band-pass analog active filters using second-generation current conveyors. It is known that filters using multiple-feedback structures have reduced sensitivities to passive component tolerances. It was shown that using the follow-the leader (FLF) topology, the sensitivity of current transfer(More)
