HIGHER ORDER MULTIFUNCTION FILTER USING CURRENT DIFFERENCING BUFFERED AMPLIFIER (CDBA)
Keywords:
Current differencing buffered amplifier (CDBA), Current feedback operational amplifier (CFOA), Active multifunction filterAbstract
This research article comes with a higher-order multifunction filter design, specifically low pass (LP), high pass (HP), and bandpass (BP) filter using a current differencing buffered amplifier (CDBA) as an active element. A general voltage transfer function can be observed in four admittance terms to facilitate the fifth-order filter function. The investigation of the proposed design is verified using PSPICE simulation using a CMOS-based CDBA structure as an active block and integrated with 0.5 µm CMOS technology parameter. To explore the effect of variations due to specific components on the proposed filters' performance has been examined along with the sensitivity, non-ideality analysis, and Monte-Carlo simulation. The simulation results are found in close agreement with the theoretical results. The proposed circuit achieved low power consumption and a low percentage of total harmonic distortion (%THD) which is suitable for low power VLSI design. The commercially available current-feedback operational amplifiers (CFOA based IC AD844AN are also used for experimental verification.
