Abstract :
Some novel multifunction biquadratic filters with voltage gain, each of which employs four current conveyors, two grounded capacitors, and three-five resistors, are presented. Each proposed circuit offers the following advantageous features: realization of different biquadratic filter signals from the same configuration, no requirements for component matching conditions, employment of only two grounded capacitors which are ideal for integration, orthogonal control of ω0 and Q and low sensitivities
