    • A low power oscillator based temperature sensor for RFID applications 

      Mohamad, Saqib; Tang, Fang; Amira, Abbes; Bermak, Amine; Benammar, Mohieddine ( IEEE Computer Society , 2013 , Conference Paper)
      In this paper we present a temperature sensor based on a ring oscillator. The ring oscillator uses the CMOS thyristor delay element and has an extremely low power consumption of about 47nW at room temperature with a supply ...

    • A multi-sensing reconfigurable platform for gas applications 

      Akbar, Muhammad Ali; Ali, Amin Ait Si; Amira, Abbes; Benammar, Mohieddine; Bensaali, Faycal; ... more authors ( IEEE , 2014 , Conference Paper)
      The production of hazardous gases due to different physicochemical reactions in gas industries have raised the need of autonomous sensor tag. However the adaptation of remotely controlled sensor tag is still suffering with ...

    • 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. ...

    • Two-step single slope/SAR ADC with error correction for CMOS image sensor 

      Tang, Fang; Bermak, Amine; Amira, Abbes; Amor Benammar, Mohieddine; He, Debiao; ... more authors ( Hindawi Publishing Corp , 2014 , Article)
      Conventional two-step ADC for CMOS image sensor requires full resolution noise performance in the first stage single slope ADC, leading to high power consumption and large chip area. This paper presents an 11-bit two-step ...
