A re-convertible circuit that can either act as a current-mode universal filter or as a fully un-coupled dual-mode singleresistance-controlled quadrature oscillator or simply works as a grounded loss-less inductor, by simple selection of appropriate passive switches, is proposed here. The proposed circuit requires a maximum of two voltage differencing current conveyors as an active element in the case of filter and oscillator application, whereas only one active device suffices the purpose of active inductor implementation. In all the cases only grounded passive elements are employed. Various regular analysis for the proposed circuits have also been included here to support the theoretical idea. The workability of these circuits has been demonstrated by practicing PSPICE simulation software with TSMC CMOS 0.18 μm process parameters along with the experimental justification of the derived application using commercially available integrated circuits.
