Design of Current Mode Active Filters Using CCCII for Biomedical Applications

Current-mode filters have garnered astonishing attention in biomedical applications owing to their inherent advantages that include low power requirement, massive bandwidth, extreme slew rate, and compact topology. These characteristics make them particularly suitable for processing low-frequency biomedical signals such as electrocardiograms (ECG), electroencephalograms (EEG), and electromyograms (EMG). First order Low Pass Filter (LPF), High Pass Filter (HPF) and All Pass Filters are anticipated utilizing CCCII (Second Generation Current Controlled Conveyor) in this manuscript. The proposed designs are tested using Transient analysis, AC analysis and Montecarlo analysis. The simulation is carried out using Cadence Orcad Tool of 17.2 version. The proposed topologies are experimentally verified using commercially available ICs AD 844AN, called as CFOA (Current Feedback Operational Amplifier) and LM 13700, termed as OTA (Operational Transconductance Amplifier). The novelty of proposed configurations is, it needs a simple circuit utilizing single CCCII and very less external passive components for realization. Filters are useful in the vicinity of Biomedical applications, continuous time signal processing, Telecommunication systems, Audio processing, Sensor interfaces, Image processing, Industrial automation, Neuromorphic circuits, Space and defense, Optical communication, and in many more areas.
