5-11 GHz CMOS PA with 158.9 ± 41 ps group delay and low power using current-reused technique
Rohana, Sapawi, Dr.; Sohiful Anuar, Zainol Murad, Dr.; Dayang Azra, Awang Mat (Elsevier GmbH, 2012-11)This paper proposes the design of a low group delay and low power ultra-wideband (UWB) power amplifier (PA) in 0.18 μm CMOS technology. The PA design employs two stages cascade with inductive peaking technique to provide ... -
Copper ion-exchanged channel waveguides optimization for optical trapping
Ali Hussain, Reshak, Prof. Dr.; Khor, Kang Nan; Mukhzeer, Mohamad Shahimin, Dr.; Sohiful Anuar, Zainol Murad, Dr. (Elsevier Ltd., 2013-08)Optical trapping of particles has become a powerful non-mechanical and non-destructive technique for precise particle positioning. The manipulation of particles in the evanescent field of a channel waveguide potentially ... -
