Abstract:

New configurations are proposed which realise multiple-input-single-output-type multifunction current mode and voltage mode biquads capable of realizing the low-pass, band-pass, high-pass, and notch functions from the same configuration using only a single current feedback op-amp, four resistors and two grounded capacitors. The new circuits offer several advantageous features over the previously known single-current feedback op-amp/second generation current conveyor-based biquads. Electronic tunability of οo is feasible by replacing the resistors by appropriately-valued CMOS voltage-controlled-resistors driven by a common external control voltage. PSPICE simulation and hardware implementation results are given which have demonstrated the workability of the proposed configurations.
