Abstract :
In this paper, a current-mode circuit for realizing high-order low-pass (LP) and high-pass (HP) filter responses is presented. The proposed circuit uses dual output second-generation current controlled conveyors (DO-CCCII) and only grounded capacitor. The coefficients of the filter transfer functions (TFs) can be tuned electronically via external biasing currents of the active elements. Also, LP and HP filters are connected in cascade to obtain a band-pass (BP) filter. Simulations are performed for fourth-order and eighth-order filter responses to illustrate the frequency domain performance of the circuit.
