Multi-Input Single-Output Universal Current Mode Biquad
Neeta Pandey and Sajal K. Paul
A configuration which can serve as a reference for realizing multi-input single-output current mode biquad is presented. The circuit employs one single output current conveyor(CCII), one dual output current conveyor (DO-CCII) and five passive components. The proposed model is simple in structure, and is capable of realizing all five generic filter functions all at high impedance output and thus enables easy cascadability. The proposed configuration also enjoys orthogonal control of pole quality factor and pole natural frequency and has low active and passive sensitivities. PSPICE simulation results are also provided.
