    • 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 ...
    • Development of varied CMOS ring oscillator topologies in 0.13-μm CMOS technology 

      Sohiful Anuar, Zainol Murad, Dr.; Rizalafande, Che Ismail, Dr.; Mukhzeer, Mohamad Shahimin, Dr.; Mohd Fairus, Ahmad; Rohana, Sapawi (Trans Tech Publications Inc., 2014)
      This paper presents varied CMOS ring oscillator topologies using Silterra 0.13-µm Process. Three topologies of ring oscillators have been designed which is the single-ended ring oscillator, differential ring oscillator and ...
    • High efficiency, good linearity, and excellent phase linearity of 3.1-4.8 GHz CMOS UWB PA with a current-reused technique 

      Sohiful Anuar, Zainol Murad; Pokharel, R. K.; Sapawi, R.; Kanaya, H.; Yoshida, K. (Institute of Electrical and Electronics Engineers (IEEE), 2010-08)
      This paper describes the design of 3.1 to 4.8 GHz CMOS power amplifier (PA) for ultra-wideband (UWB) applications using 0.18-m CMOS technology. The UWB PA proposed here employs cascode topology with a currentreused technique ...
    • Improved subtraction function for logarithmic number system 

      Rizalafande, Che Ismail, Dr.; Sohiful Anuar, Zainol Murad, Dr.; Razaidi, Hussin; Coleman, John Nicholas (Elsevier Ltd., 2013)
      Logarithmic number system can be highly considered as an alternative to floating-point, specifically for applications that require a wide dynamic range of numbers for their arithmetic operations. To date, its implementation ...
    • Linearity improvement of 5.2-GHz CMOS up-conversion mixer for wireless applications 

      Sohiful Anuar, Zainol Murad, Dr.; Mukhzeer, Mohamad Shahimin, Dr.; Pokharel, Ramesh Kumar, Prof.; Kanaya, Haruichi, Assoc. Prof.; Yoshida, Keiji, Prof (John Wiley & Sons, Inc., 2012-04)
      This letter presents linearity improvement up-conversion mixer at 5.2 GHz for wireless applications. The design is based on Gilbert-cell active double-balanced mixer using derivative superposition method for linearity ...
    • Simulation of Brillouin and Rayleigh scattering in distributed fibre optic for temperature and strain sensing application 

      Ali Hussain, Reshak, Prof. Dr.; Mukhzeer, Mohamad Shahimin, Dr.; Sohiful Anuar, Zainol Murad, Dr.; S., Azizan (Elsevier B.V., 2013)
      This paper presents simulations of a distributed fibre optic sensor for temperature and strain sensing. The behaviours of Brillouin and Rayleigh scattering in optical fibres are studied through the backscatter signals. The ...
