About Me
Ahmed S. Emara received his B.Sc. and M.Sc. in Electronics and Communications Engineering from the American University in Cairo, Cairo, Egypt in 2014 and 2016, respectively, and the Ph.D. degree in Electrical and Computer Engineering from McGill University, Montreal, Quebec, Canada in 2021. Part of his Ph.D. research was done in conjunction with Ciena Corporation, Ottawa, Ontario, Canada.
Currently, Ahmed holds the position of staff analog and mixed-signal design engineer at Synopsys in Mississauga, Ontario, Canada. In this role, his primary focus is on designing and verifying various building blocks within the SerDes transmitter, ensuring compliance with PCIe6 and E112 standards.
He has authored or co-authored around 20 papers in scientific journals, conferences and currently holds a US patent. His main research interests include analog and mixed-signal IC design and test.
