Muhammad Ahmed received his B.Sc. and M.Sc. degrees in electrical engineering from Ain Shams University, Cairo, Egypt, in 2010 and 2015 respectively. From 2010 to 2015 he was as a senior Analog/Mixed Signal Design Engineer at MEMS Vision LLC, Cairo, Egypt, where he worked on the development of high-performance Phase Locked Loops, low-power Opamps and comparators, and linear power regulators (LDOs). Muhammad joined PMRL in 2015 to pursue his Ph.D. degree. His current research interests include high-frequency switching power converters and modulators, high PSRR low drop-out regulators, frequency synthesizers, digital phase-locked loops, digital fractional multiplying delay-locked loops, digital-to-time converters, and low-power mixed-signal circuits.
