Abstract

Recently, the active-R circuits utilizing the current feedback op-amps (CFOA)-pole have been shown to be superior alternatives to the active-R circuits designed using the compensation-poles of the traditional voltage-mode op-amps. The object of this brief, is to present some new CFOA-pole-based active-R circuits which employ a very small number of active and passive components, and yet, offer features which have not been attained simultaneously from any of the previously known active-R circuits using CFOA-poles such as, noninteracting controls of parameters, and the availability of the intended properties, in spite of the presence and consideration of all the parasitics (even other than those forming CFOA-pole). The workability of the proposed circuits has been confirmed by PSPICE simulations and hardware implementations based on AD844 type CFOAs
