Jitendra Mohan, Sudhanshu Maheshwari, Sajai V. Singh and Durg S. Chauhan
A new single input and five outputs voltage-mode universal biquadratic filter with high-input impedance using four plus-type DVCCs, two grounded capacitors and two grounded resistors is presented. The proposed circuit offers the following features: realization of all the standard filter functions, that is, high-pass, band-pass, low-pas, notch and all-pass filters simultaneously without component matching conditions, the use of grounded components and high input impedance.
