New configuration for the design of biquad filters with positive feedback topology is presented. The configuration can synthesize low-pass, high-pass and band-pass filter functions according to the passive components used in circuits. The proposed configuration employs only one FDCFOA as active element and minimum number of passive elements, namely two capacitors and resistors. SPICE simulation results are given to confirm the validity of the analysis and to point out the high performance of the filters. The output of the filter exhibits high output impedance so that the synthesized filter can be cascaded without additional buffers.
