Objectives: In the Current era, current conveyors become the most crucial design. In this paper, a multipurpose filter which acts as low pass, high pass, band pass, all pass and notch is presented. This design of multipurpose filter is based on DOCCCII. Methods/Statistical Analysis: The band width of the presented filter will depend on dc bias currents electronically. SPICE simulations of this multipurpose filter have been done using TSMC 0.35 µm CMOS process parameters. Findings: This filter circuit uses only two capacitors. The benefit of using this circuit is that it is electronically tunable. In these work different parameters of universal filter has been calculated and also simulated using CMOS process parameters. Application/Improvements: By making change in W/L ratios simulation results can be enhanced. Device can be made compact by reducing channel length and hence the power dissipation of device will be low and we can get better results.
Keywords: Universal Filter, DOCCCII, SPICE simulation, 0.35 µm CMOS process parameters and tunable
