A Variable High Q Notch Filter Using FTFN’s
Reshu Agarwal, Kirat Pal and R. K. Sharma

A new configuration for realizing voltage mode variable Q band notch filter using two FTFN has been reported in this paper. The present configuration offers notch filter of desired Q by proper design. The circuit uses two FTFN’s, two resistors and three capacitors. The simulated results are found in good agreement with the theoretical analysis.
