Biography Summary

Bosco Leung is a Professor in the Department of Electrical and Computer Engineering at the University of Waterloo.

His research interests include the design of mixed analog/digital circuits for wireless communication and the noise model on nonlinear circuits (including phase noise of oscillator and quantum noise of time to digital converter for qubit readout).

Professor Leung is the author of ‘VLSI for Wireless Communication’ 2nd edition (2011, Springer Verlag), 1st edition (2002, Prentice Hall). He also holds several US patents on sigma delta circuits.
