    • A comparative analysis between logarithmic number system and floating-point ALU 

      Rizalafande, Che Ismail, Dr.; Coleman, John Nicholas; Norzahiyah, Nordin; Zaliman, Sauli, Dr. (AENSI Publisher All rights reserved, 2013-10)
      The ease and accuracy of executing the multiplication and division operations by using either fixed-point addition or subtraction is what makes the logarithmic number system an attractive option. However, its main drawback ...

    • 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 linearity on-chip mixer for 46 LTE wireless communication 

      Sohiful Anuar, Zainol Murad, Dr.; Rizalafande, Che Ismail, Dr.; Mohd Nazrin, Md Isa, Dr.; Mukhzeer, Mohamad Shahimin, Dr.; Asral Bahari, Jambek, Dr.; Norhawati, Ahmad, Dr.; Amiza, Rasmi (Universiti Malaysia Perlis (UniMAP)School of Microelectronic Engineering, 2014-05)
      The growth of 4G wireless communication system, a high performances, simple circuitry and low cost wireless transmitters are required. One of the main radio frequency (RF) circuits in the wireless communication transmitter ...

    • High performance video graphic architecture using hybrid logarithmic system 

      Rizalafande, Che Ismail, Dr.; Sohiful Anuar, Zainol Murad, Dr.; Mohd Nazrin, Md Isa, Dr.; Asral Bahari, Jambek, Dr.; Phak Len, Eh Kan, Dr.; Fazrul Faiz, Zakaria; Mohd Fikri Che Husin (Universiti Malaysia Perlis (UniMAP)School of Microelectronic Engineering, 2014-05)
      It is known that the engines generate an image from a scene described as a list of vertices, a list of triangles and the position of the camera. The transformation stage transforms the vertices from the scene coordinates ...

    • Improved addition and subtraction in logarithmic number system: Technique and analysis 

      Rizalafande, Che Ismail, Dr.; Norzahiyah, Nordin; Asral, Bahari Jambek, Dr. (AENSI Publisher All rights reserved, 2013-10)
      Logarithmic Number System (LNS) is an alternative beside Floating Point (FLP) when an application requires a large dynamic range in the number processed. It allows simple implementation of multiplication and division using ...

    • Improved subtraction function for logarithmic number system 

      Rizalafande, Che Ismail, Dr.; Sohiful Anuar, Zainol Murad, Dr.; Hussin, R. (Malaysian Technical Universities Network (MTUN), 2012-11-20)
      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 ...
