    Abstract : Internet of Things is expanding to the areas such as healthcare, home management, industrial, agriculture, and becoming pervasive in our life, resulting in improved efficiency, accuracy and economic benefits. Smart sensors with embedded interfacing integrated circuits (ICs) are important enablers, hence, variety of smart sensors are required. READ MORE

  4. 2. Floating-Point Analog-to-Digital Converter

    Author : Johan Piper; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics and Electrical technology; matching; binary weighting; dynamic range; resolution; distortion; pipeline; A D-converter; floating-point; Elektronik och elektroteknik;

    Abstract : To deal with the wide dynamic rage necessary for a radio receiver or corresponding applications, but to avoid impractically high resolution at high data rates, the approach of using a floating-point analog-to-digital converter (FP-ADC) has been investigated. This approach de-links the dynamic range with the resolution, and a very wide dynamic range can be achieved by an ADC with a moderate resolution. READ MORE

  5. 3. Modeling and post-correction of pipeline analog-digital converters

    Author : Samer Medawar; Peter Händel; Martin Gustafsson; KTH; []
    Keywords : ;

    Abstract : Integral nonlinearity (INL) for pipelined analog-digital converters (ADCs) operating at radio frequency is measured and characterized. A parametric model for the INL of pipelined ADCs is proposed and the corresponding least-squares problem is formulated and solved. READ MORE

  6. 4. Energy-Efficient Data Converters for Low-Power Sensors

    Author : Kairang Chen; Atila Alvandpour; Ana Rusu; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Wireless sensor networks (WSNs) are employed in many applications, such as for monitoring bio-potential signals and environmental information. These applications require high-resolution (> 12-bit) analog-to-digital converters (ADCs) at low-sampling rates (several kS/s). READ MORE

  7. 5. CMOS Aid Converters For Telecommunications

    Author : Mikael Gustavsson; Mohammed Ismail; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In many telecommunications applications, as mobile radio and internet access, analog filters and data converters are needed. The data converters are crucial building blocks that strongly influence the performance and price of the whole system. READ MORE
