Paper Abstract

A novel multifunction second order current-mode filter employing two multiple output second-generation current controlled conveyors (MO-CCCII) and only two grounded capacitors is presented. The proposed circuit can simultaneously realize low-pass (LP), band-pass (BP), band-stop (BS) and high-pass (HP) filter functions from the same configuration without critical matching conditions. It can also realize all-pass (AP) filter function just by connecting the output currents ILP, IBP and IHP without using any additional element. Electronic tunability for ω0 and Q through adjusting the bias current of the MO-CCCII. Additionally, grounded capacitor is attractive for integration. A sensitivity analysis shows that the filter has low active and passive sensitivities. In the last, PSPICE simulation results are given to verify theoretical analysis.
