PhD thesis discusses simulation and performance analysis of broadband solid-state devices for high frequency applications

On Wednesday, January 7, 2026, the doctoral thesis submitted by the student Muhannad Moayed Elias, entitled ” simulation and analysis of the performance of broadband solid – state devices for high-frequency applications”, was discussed at the Physics Department of the College of Sciences-University of Mosul .
The thesis aimed to simulate and analyze the performance of inter-impedance amplifiers used in optical receivers, by proposing three different designs depending on CMOS technology with a channel length of 45 Nm and an operating voltage of 1 V, while achieving an optimal balance between gain, bandwidth, input noise and power consumption. Mathematical analysis was adopted along with the ADS simulation program to confirm the results and the behavior of the proposed circuits.
The results of the study showed the efficiency of the proposed designs in achieving high profit with low energy consumption, as the profit values ranged from 56.8 dBΩ to more than 66 dBΩ at a bandwidth of 1GHz, and with a low power consumption did not exceed 1 milliwatt, with a noticeable improvement in the characteristics of input noise.
The discussion committee consisted of:
Dr. Abdullah Idris Mustafa (Chairman)
Professor Dr. Yasser Abdul-Jawad Abdullah (member)
Assistant professor Dr. Ahmed Walid Kassem (member)
Assistant professor Dr. Abdul Khaliq Ayoub Suleiman (member)
Assistant professor Dr. Mohammed Mahmoud Younis (member)
Prof. Dr. Mohamed Sobhi Hamid (member and supervisor)
At the end of the discussion, the head of the physics department, assistant professor Dr. Samir Mahmoud Ahmed, presented a letter of thanks and appreciation to assistant professor Dr. Ahmed Walid Kassem from the northern Technical University/Engineering Technical College, in appreciation of his participation in the discussion Committee.
The College of science wished the student and the professors continued success and giving in the service of the scientific career.
