  2. 1. 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

  4. 2. Ultra-low Voltage Embedded Memories – Design Aspects and a Biomedical Use-case

    Author : Oskar Andersson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRAM; CMOS; ultra-low voltage; ultra-low power; subthreshold; standard-cell based memories; atrial fibrillation; SRAM; CMOS; ultra-low voltage; ultra-low power; subthreshold; standard-cell based memories; atrial fibrillation;

    Abstract : As the Internet of Things (IoT) era emerges the need for ultra-low power (ULP) devices is becoming more eminent. A research-proven approach to achieve ULP consumption is to aggressively lower the supply voltage (VDD) below or in the vicinity of the transistor threshold voltage (Vth) and operate the transistors in the subthreshold (sub-Vth) region.

  5. 3. Design Space Exploration of Digital Circuits for Ultra-low Energy Dissipation

    Author : Syed Muhammad Yasser Sherazi; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; ultra low-voltage; ultra low-energy; subthreshold sub-VT ; body biasing; pipelining; unfolding; half-band digital filter.;

    Abstract : The ever expanding market of ultra portable electronic products is compelling the designer to invest major efforts in the development of small and low energy electronic devices. The driving force and benefactors of such devices are (but not limited to) e-health system, sensor network applications, security systems, environmental applications, and home automation systems.

  6. 4. Low-Power Delta-Sigma Modulators for Medical Applications

    Author : Ali Fazli Yeknami; Atila Alvandpour; Martin Anderson; Linköpings universitet; []
    Keywords : ;

    Abstract : Biomedical electronics has gained significant attention in healthcare. A general biomedical device comprises energy source, analog-to-digital conversion (ADC), digital signal processing, and communication subsystem, each of which must be designed for minimum energy consumption to adhere to the stringent energy constraint.

  7. 5. Ultra-low-power Design and Implementation of Application-specific Instruction-set Processors for Ubiquitous Sensing and Computing

    Author : Ning Ma; Lirong Zheng; Zhonghai Lu; Zhuo Zou; Jari Nurmi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The feature size of transistors keeps shrinking with the development of technology, which enables ubiquitous sensing and computing. However, with the break down of Dennard scaling caused by the difficulties for further lowering supply voltage, the power density increases significantly. READ MORE
