• Calibration & Temperature Controlled Setup for Air Quality Sensors 

      Ijaz, Ali; Benammar, Mohieddine Amor; Touati, Farid; Kadri, Abdullah ( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)
      Indoor air pollution is a major issue affecting public health. Due to hot climate, humidity and lack of natural green spaces, life is mostly confined indoors in many countries of the MENA region. Vulnerable population, ...
    • Continuous-Time ΣΔ ADC with Implicit Variable Gain Amplifier for CMOS Image Sensor 

      Tang, Fang; Bermak, Amine; Abbes, Amira; Benammar, Mohieddine Amor ( Hindawi Publishing Corporation , 2014 , Article)
      This paper presents a column-parallel continuous-time sigma delta (CTSD) ADC for mega-pixel resolution CMOS image sensor (CIS). The sigma delta modulator is implemented with a 2nd order resistor/capacitor-based loop filter. ...
    • Determining the Outdoor Air Ventilation with Carbon Dioxide (CO2) as a Tracer Gas 

      Ijaz, Ali; Benammar, Mohieddine Amor; Touati, Farid; Kadri, Abdullah ( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)
      Insufficient ventilation can lead to occupant complaints of discomfort and reduced productivity as human and building generated pollutants build up. Some combinations of these elevated pollutants may have short or long-term ...
    • Impact of feature reduction and operating temperature on gas identification 

      Akbar, Muhammad Ali; Ali, Amine Ait Si; Amira, Abbes; Bensaali, Faycal; Benammar, Mohieddine Amor; ... more authors ( Asian Research Publishing Network , 2015 , Article)
      Tin-oxide based gas sensor requires an operating temperature typically in the range of 200 °C to 400 °C and its performance dependents on this temperature. In this paper a deep examination has been made to analyze the best ...
