Dawei Mai received the Ph.D. degree in electrical and electronic engineering from University College Dublin in 2021. He has published extensively in the field of fractional-N frequency synthesis. He is an expert in the modeling, simulation and analysis of nonlinearity-induced phenomena in frequency synthesizers. He contributed to the analysis of the wandering spur phenomenon in fractional-N frequency synthesizers and invented an effective technique to mitigate wandering spurs. Michael Peter Kennedy FIEEE received the Ph.D. degree from the University of California at Berkeley and the D.Eng. degree from the National University of Ireland. He has made seminal contributions in the fields of neural networks, chaotic oscillators, chaos communications, mixed-signal testing, digital delta-sigma modulation, and frequency synthesis. He is Professor of Microelectronic Engineering at University College Dublin and Scientific Director of the Microelectronic Circuits CentreIreland.
