Head of the Electrical Engineering Department at the College of Engineering, University of Kirkuk, Publishes a Research Paper at an International Conference

Dr. Arsan Ahmed Mohammed, Head of the Electrical Engineering Department at the College of Engineering, University of Kirkuk, has published a scientific research paper at the International Conference on Robotics, Automation, and Smart Computing, organized by AIP Publishing.

The paper, titled “Enhanced Design and Analysis of a Quad-Function Oscillator and Dual-Function Filter Using FinFET Transistors in a Current-Mode Filter Circuit”, presents an innovative design for a current-mode frequency filter circuit that features low power consumption, making it ideal for use in wireless communication systems. The circuit supports multiple functions, including high-pass, low-pass, and band-pass filtering, with independent tuning of the quality factor and cutoff frequency.

Simulation results using LT-SPICE and Cadence Virtuoso demonstrated that the design consumes only 285 µW at an operating voltage of 0.1V, enhancing energy efficiency in portable electronic systems.

The design is based on two CC-CDTA amplifiers and only two capacitors, making it easily integrable into ICs, thus opening new possibilities for high-efficiency, low-power frequency filters.

This research represents a significant scientific contribution to the development of modern electronic circuit designs, particularly in wireless communication systems that require high performance with minimal power consumption.
