Voltage Mode Tow Thomas Universal Filter: a Current Controlled Conveyor Approach
نویسندگان
چکیده
In this paper, Tow Thomas universal filter based on current controlled conveyor (CCCII) is presented. The proposed configuration utilizes six CCCII-s, two grounded capacitors and two grounded resistors. The circuit enjoys a number of advantages: composed of solely minus type of current conveyors, offers high input impedance, uses all grounded passive components, independent electronic control of ω0, Q0, and gain with biasing currents of CCCII-s and grounded resistor. The filter also exhibits low sensitivity with respect to passive components. PSPICE simulation results are included to verify theory.
