SIMO Type Voltage-Mode Biquadratic Multifunction Filter

A new circuit of voltage-mode biquadratic multifunction filter based on fully differential second generation current conveyor (FDCCII) is introduced in this paper. It is realized using one FDCCII, three resistors and two capacitors. The filtering functions namely, low-pass, high-pass, band-pass and band-reject (LP, HP, BP and BR, respectively) are simultaneously realizable from proposed biquadratic multifunction filter. The proposed biquadratic multifunction filter realizes the filtering responses without need of any component matching constraints. The non-ideal aspects of biquadratic multifunction filter circuit are also studied. The performance of the circuit of biquadratic multifunction filter is examined with the help of HSPICE simulations.
