MO-CCCII High-Order Chebyshev Notch Filter

This article presents the design of a high-order Chebyshev notch filter using Multiple Output Current Controlled Conveyor (MO-CCCII). In this design process, the RLC high-order low-pass Chebyshev filter prototype is initially converted into a notch filter by using network transform. Subsequently, passive network analyses were performed using Kirchhoff's Current Law (KCL) method and Signal Flow Graph (SFG). Lossy and lossless integrators/differentiators using MO-CCCIIs are designed to substitute in the SFG. The performances of the proposed circuit are simulated by using PSpice. The proposed filter can effectively reject the frequency 50Hz-80Hz. The results also provide the electronically tunable feature by removing the powerline interference of 50Hz and 60Hz systems in biosensor applications.
