  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
