Abstract
This paper proposed a novel four-input four-output current-mode employing two grounded capacitors and two current differencing transconductance amplifiers (CDTAs) from a universal filter and it has been done. The filter could implement five filtering functions on a single topology. The conditions of passive component-matching and requirements of inverting-type input signal are absent in implementing of these filtering functions. The bias currents could control the natural frequency electronically meanwhile the filter passive and active sensitivities are low. To confirm between both the proposed filter and presented theory, the PSPICE simulation results were taken and carried out.
