  1. 1. The Buried Oxide of Silicon on Insulator Materials

    Författare :Per Ericsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxide defects; internal oxidation; aluminum oxide; wafer bonding; SOI; silicon on insulator; buried oxide;

    Sammanfattning : The buried oxide of silicon on insulator (SOI) wafers plays an important role in the operation of electronic devices made on such materials. The presence of defects in the buried oxide can seriously degrade the performance of a circuit. LÄS MER

  3. 2. Submillimeter-Wave Waveguide Frontends by Silicon-on-Insulator Micromachining

    Författare :Adrian Gomez-Torrent; Joachim Oberhammer; Umer Shah; Goutam Chattopadhyay; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antenna; orthomode transducer; switch; waveguide; radiofrequency; beamforming network; submillimeter-wave; terahertz; silicon micromachining; deep reactive ion etching; silicon on insulator; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : This thesis presents novel radiofrequency (RF) frontend components in the submillimeter-wave (sub-mmW) range implemented by silicon micromachining, or deep reactive ion etching (DRIE). DRIE is rapidly becoming a driving technology for the fabrication of waveguide components and systems when approaching the terahertz (THz) frequency range. LÄS MER

  5. 4. Implementation of Flash Analog-to-Digital Converters in Silicon-on-Insulator Technology

    Författare :Erik Säll; Mark Vesterbacka; Bengt E. Jonsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flash analog-to-digital converter; ADC; silicon-on-insulator; SOI; top-down design; dynamic element matching; DEM; thermometer-to-binary encoder; flash ADC modeling; Electronics; Elektronik;

    Sammanfattning : High speed analog-to-digital converters (ADCs) used in, e.g., read channel and ultra wideband (UWB) applications are often based on a flash topology. The read channel applications is the intended application of this work, where a part of the work covers the design of two different types of 6-bit flash ADCs. LÄS MER

  7. 5. Implementation of Flash Analog-to-Digital Converters in Silicon-on-Insulator CMOS Technology

    Författare :Erik Säll; Mark Vesterbacka; Bengt E. Jonsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analog-to-digital converters; ADC; silicon-on-insulator; SOI; Electronics; Elektronik;

    Sammanfattning : A 130 nm partially depleted silicon-on-insulator (SOI) complementary metal oxide semiconductor (CMOS) technology is evaluated with respect to analog circuit implementation. We perform the evaluation through implementation of three flash analog-to-digital converters (ADCs). LÄS MER
