An extra-X second-generation current conveyor (EXCCII) based first-order current-mode all-pass frequency selective structure is presented through this paper. A grounded resistor and a grounded capacitor are used as passive components. Single active element based realization directly correlates with the circuit’s simplicity. The grounded nature of passive components is advantageous from IC fabrication aspects. The proposed circuit offers cascadability support through low input impedance and high output impedance. The ability of the presented idea to deliver the desired output without meeting any stringent component matching condition further simplifies the circuit’s operation. Sensitivity performance of the proposed circuit is good. The quality performance at high frequency is another value addition to the circuit’s signal processing attributes. Analyses showing the circuit’s behavior under non-ideal conditions are also described in detail. Validation of theoretical analyses is supported by simulations carried out on PSPICE at 0.25μm technology.
