Realisation of higher order filter using Current Conveyors

In this paper, two low component count Voltage Mode (VM) and Current Mode (CM) higher order filters are proposed. The higher order filters are derived from second order filter module, which are realised by using Second Generation Current Conveyors (CCII). Both the filter modules have low component count and lower sensitivity figure. Apart from this, both the modules provide the feature of cascadability, which is required for realisation of higher order filter function. Performances of all the proposed circuits are verified by PSPICE simulation using TSMC 0.25μm technology parameters.
