Özet

In this study, an electronically tunable differential difference current conveyor is presented. The benefits of this new active element are demonstrated on tunable first-order voltage-mode all-pass filter employing a resistor and a capacitor. In the proposed filter structure using single active and two passive elements no element-matching restriction is required. The theoretical results are verified with SPICE simulations using TSMC 0.35 mu m CMOS process parameters and with +/- 2.5 V supply voltages.
