Abstract Current-mode multifunction biquardratic niters based on current controlled conveyor (CCCII) with two grounded capacitors is proposed. The circuit offers the following advantageous features: realization of different biquadratic filter signals from the same configuration employment of only two grounded capacitors which are ideal for integration, orthogonal control of ω0 and Q, and low sensitivities.
