  5. 3. Design of Ultra-Low-Power Analog-to-Digital Converters

    Author : Dai Zhang; Atila Alvandpour; Trond Ytterdal; Linköpings universitet; []
    Keywords : analog-to-digital converter; ADC; successive approximation register; SAR; SAR ADC; ultra-low-power; power consumption bounds; medical implant devices;

    Abstract : Power consumption is one of the main design constraints in today’s integrated circuits. For systems powered by small non-rechargeable batteries over their entire lifetime, such as medical implant devices, ultra-low power consumption is paramount. READ MORE

  6. 4. Power Estimation and Low Power CMOS Circuit Techniques

    Author : Atila Alvandpour; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The increasing power consumption due to the high integration rate of VLSI digital CMOS circuits has become a major concern. Many important design issues and parameters are strongly dependent on the power dissipation and the accuracy of its estimated value during the design exploration. READ MORE

  7. 5. Distributed Clocking and Clock Generation in Digital CMOS SoC ASICs

    Author : Thomas Olsson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik; dual supply voltage; clock generator; digital; VHDL; CMOS; low-power; Distributed clocking; PLL;

    Abstract : With shrinking technologies and higher clock rates comes the possibility to transform multi chip implementations to a single System on Chip (SoC). Implementing clock distribution and limiting the power consumption becomes increasingly troublesome with increased clock rate and chip area. READ MORE
