dc.description.abstractThis article described a compact structure simulating electronically controlled high-order Elliptic filter based on OTA-C. The signal flow graph (SFG) is deployed as a synthesis method from RLC prototype. The synthesis of Elliptic filter using SFG is normally required the integrators and very low current/voltage gain. This proposed filter is synthesized by using SFG and no required any current/voltage gains. From its SFG, the OTA-C based integrators and differentiators can be realized. The completed circuit is using only grounded capacitors with low-complexity structure. The frequency response of proposed filter can be tuned through the equality of OTA's bias currents. The supply voltage is using ±. The comparison of proposed filter and RLC prototype characteristics are verified by PSpice that the results are in good agreement.
