Abstract
This study presents a new current-mode singleinput and multi-output (SIMO) type universal biquad circuit using second generation multi-output current conveyors (MOCCII) as the active components. The proposed circuit employs three MOCCIIs, two grounded capacitors and four grounded resistors, therefore offers electroning tuning possibilities. It can simultaneously realize second order low-pass, band-pass, high-pass, notch and all-pass filters. The circuit is cascadable and has low sensitivities. It provides independent control of ω0 (natural angular frequency) and Q (quality factor). The influences of MOCCII parasitic elements have been analyzed and simulated using PSPICE. Experimental results including frequency responses of low-pass, high-pass, band-pass and band-stop filters, as well as frequency responses of filters with different ω0 (keeping Q invariable) and different Q (keeping ω0 invariable) are shown to be in agreement with theory.
