  1. 1. Manufacturability in the Nanometer Era: Regularity considerations in VLSI Circuits

    Författare :Kasyab Parmesh Subramaniyan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Regular Fabrics; Shifters; Barrel Shifter; ASIC; TDM; Bricks; Wired; Transistor; VLSI.; Multipliers; CMOS; HPM; Regularity; SoC; Arithmetic; Circuits;

    Sammanfattning : Each reduction of the technology node has, along with improvements in IC fabricationtechnology, been the main driver in delivering the demand for function rich, integratedmobile electronics that are so prevalent. As devices keep growing smaller and geometriesapproach the order of a few atomic layers, it is increasingly difficult to achievecost-effective mass production for reasons related to performance and fabrication capability.

  5. 4. Integrated Antennas : Monolithic and Hybrid Approaches

    Författare :Erik Öjefors; Anders Rydberg; Sayan Mukherjee; Duixian Liu; Uppsala universitet; []
    Nyckelord :Electronics; antenna travelling wave arrays; antenna phased arrays; phase shifters; micromachining; silicon; monolithic microwave integrated circuits; dipole antennas; loop antennas; slot antennas; Elektronik;

    Sammanfattning : This thesis considers integration of antennas and active electronics manufactured on the same substrate. The main topic is on-chip antennas for commercial silicon processes, but hybrid integration using printed circuit board technology is also addressed. LÄS MER

  7. 5. Exploring the potentials of next-generation, wavelength-shifting, optical sensors for IceCube

    Författare :Jakob Beise; Erin O'Sullivan; Christian Ohm; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Neutrino Physics; Astroparticle Physics; Supernovae; Wavelength Shifters; IceCube;

    Sammanfattning : The IceCube Neutrino Observatory has sensitivity to MeV electron antineutrinos from core-collapse supernovae through an excess of the detection rate over the background. Wavelength-shifting sensors have the potential to greatly increase photon collection making it a promising candidate for improving the measurement of the supernova neutrino light curve in IceCube-Gen2.
