An All Pass Tunable Universal Filter Based on Second Generation Dual Output Current Controlled Conveyor (DOCCCII)

Current mode VLSI devices such as current conveyors have established their identity as the most demanding devices in the area of signal processing due to their high bandwidth, greater linearity, larger dynamic range, low power consumption, simple circuitry and occupy less chip area. CCCIIs are widely used as basic active building blocks to realize various current-mode active filters. The universal filter is among the most popular analog filters as it can provide several standard functions like low pass, high pass, band pass, and band reject and all pass In this paper we have proposed a Tunable Universal Filter that employs the use of only Current Controlled Conveyors and Capacitors. Various simulations have been carried out to obtain the desired results. The outcomes show that the proposed circuit works well as an All Pass Tunable Universal filter.
