Multi-functional electronically tunable filter using new DXCCCII

This work presents electronically tunable multi-functional three input single output second-order filter using new proposed dual-X current controlled current conveyor (DXCCCII). The multifunctional voltage mode filter offers electronically tunable realization of LP, HP, BP, and BR filters at the single output, with the use of only one active and two passive components. The filter also offers independent pole frequency control with quality factor, through a single bias current. The non-ideal gain effects of DXCCCII are also examined. Verification is carried out using 180nm technology process parameters.
