Abstract :
A new universal active current filter with single input and three outputs using only five current conveyors, two grounded capacitors and three grounded resistors is presented. The proposed circuit offers the following advantageous features: universal current-mode filter realisation from the same configuration, no requirement for critical component matching conditions/cancellation constraints, orthogonal control of omega 0 and Q through grounded resistors, and use of only two grounded capacitors which is ideal for IC implementation.
