1. 1. Static Power Reduction and Estimation in CMOS Circuits Considering Emerging Leakage Mechanisms

   Författare :Mindaugas Drazdziulis; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; subthreshold; CMOS; wake-up time; power gating; gate leakage; VLSI;

   Sammanfattning : Due to semiconductor technology advancements, the static power dissipation caused by leakage currents in CMOS circuits is growing at a much faster rate than dynamic power; the dominant power component. As a result, controlling and limiting static power becomes as crucial as controlling dynamic power. LÄS MER

3. 2. 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.

   Sammanfattning : High electron mobility transistor (InP HEMT) cryogenic low noise amplifiers (LNAs) have made significant improvements in noise and gain following decades of development. Applications are found from radio astronomy to quantum computing. LÄS MER

5. 4. Statistical and Dynamical Aspects of Intermediate Energy Nuclear Collisions

   Författare :Roberta Ghetti; Fysiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; excitation function.; subthreshold pions; pion production; neutron cross-talk; correlation function; interferometry; intermittency; phase transition; thermal scaling; reducibility; multifragmentation; Heavy ion collisions; intermediate energy; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:1997:Ghetti;

   Sammanfattning : Studies of intermediate energy heavy ion reactions have revealed the existence of a number of reducibility and thermal scaling properties in nuclear multifragmentation. In particular, the probability of emitting n-fragments is reducible to the probability of emitting a single fragment through the binomial distribution. LÄS MER

7. 5. Performance of Digital Floating-Gate Circuits Operating at Subthreshold Power Supply Voltages

   Författare :Jon Alfredsson; Bengt Oelmann; Dag Wisland; Mittuniversitetet; []
