Abstract :
The authors present two new filter biquads based on the recently introduced fully differential current conveyor (FDCCII). The biquads use a single FDCCII, two grounded resistors and two grounded capacitors, which are the minimum components necessary to realise a second-order filtering response (low-pass, high-pass, band-pass, band-reject, and all-pass). This is unlike biquads reported by El-Adawy et al. (2000), which employ more active and passive components. Simulation results are included, validating the theoretical analysis
