Indian journal of pure & applied physics (IJPAP)Summary: A novel first order lowpass (LP) and Highpass (HP) filter using VDTA and operational amplifier is presented. It is a new kind of filter structure as it uses pole model of OA and VDTA. The OA pole model as a design parameter has been successfully utilized for realization of filters resulting high performance filters. The proposed circuit uses minimum number of components. The filter offers electronic tunability of the pole frequency which is highly required in IC technology. The sensitivities of the circuit are low. The workability of the proposed filter is verified using PSPICE simulation.
