Research

I have involved in various projects within Analog and Digital domains. Currently, I am working for Intel Technologies as a CAD Engineer. Previously, I worked as Research Assistant in University College Cork where I involved in two different projects. In 2016 - 2018, I was working on the design of PAM-4 Ser-Des Systems including circuit design, prototyping, hardware system design development, characterization, MATLAB simulation, product development, and testing of PAM-4 ser-des system for high-speed data communications applications. In 2013 - 2015, I was fully involved in the development of Phase Lock Loop Systems including circuit design, characterization, simulation, prototyping, hardware development, and testing of frequency synthesizers using high speed oscilloscope and FPGA modules, phase-locking for high-speed data communications applications. However, between those two projects in 2015 - 2016, I worked for NXP Semiconductors as a Sr. Analog/Digital IC Design Engineer. At that time, I was working on the development of Security Cells including circuit design, characterization, simulation, prototyping, software/hardware development, and testing of latch sensor and high speed secure flip-flops (DFF).

In 2013, I was carrying out an international research at Interuniversity Microelectronics Centre (IMEC), Belgium supervised by Dr. Refet Firat Yazicioglu & Prof. Chris Van Hoof under international scholar grants from Katholieke Universiteit Leuven, Belgium. My researches are focused on design and characterization of a novel uni-polar three electrodes measurement for wireless bio-potential sensor for an ECG active electrode implementation. Our contribution would be twofold: (i) algorithm development for generating the computed ECG signals for reconstruct the ECG leads signals and (ii) characterization and medical validation of new novel ECG unipolar measurement methods.
