New Realization of Multi-function Filter using Bulk-Driven Differential Difference Current Conveyor

In this article, a novel structure of voltage mode multifunction filter is proposed. The proposed circuit use two BD-DDCC and four number of passive components; two resistances and two capacitances. Proposed circuit realizes low-pass, high-pass and band-pass responses from the same topology. The non-ideality and sensitivity analysis of the circuits are also included. The theoretical results are verified with PSPICE simulation using 180nm CMOS process parameters provided by TSMC. Frequency responses for the presented filters are shown in the paper. Simulation results agree well with the theoretical values. Moreover the proposed circuit consumes very low power merely 37.1μW.
