  1. 1. Ultra-low Power Design Approaches in Memories and Assist Techniques

    Författare :Babak Mohammadi; Integrerade elektroniksystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Memory; SRAM; assist technique; charge pump; ULP; ULV;

    Sammanfattning : The need for more functionality and higher performance has increased the number of transistors to billions in current processors. A high number of transistors on the same chip area increases the power density, which in turn heats up the devices and lowers the life time of batteries. LÄS MER

  3. 2. Subspace Computations via Matrix Decompositions and Geometric Optimization

    Författare :Lennart Simonsson; Axel Ruhe; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Numerical Analysis; Rank-revealing UTV; Jacobi-Davidson algorithm; Decomposition; Grassmann type algorithms; Numerical analysis; Numerisk analys;

    Sammanfattning : This thesis is concerned with the computation of certain subspaces connected to a given matrix, where the closely related problem of approximating the matrix with one of lower rank is given special attention. To determine the rank and obtain bases for fundamental subspaces such as the range and null space of a matrix, computing the singular value decomposition (SVD) is the standard method. LÄS MER

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

    Författare :Oskar Andersson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :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;

    Sammanfattning : 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.
