  3. 27. Design and Characterization of RF-LDMOS Transistors and Si-on-SiC Hybrid Substrates

    Författare :Sara Lotfi; Jörgen Olsson; Örjan Vallin; Jean-Pierre Raskin; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LDMOS; RF; losses; crosstalk; silicon carbide; Si-on-SiC hybrid substrate; wafer bonding; CMOS; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : With increasing amount of user data and applications in wireless communication technology, demands are growing on performance and fabrication costs. One way to decrease cost is to integrate the building blocks in an RF system where digital blocks and high power amplifiers then are combined on one chip. LÄS MER

  4. 28. High-Speed Analog-to-Digital Converters in CMOS

    Författare :Siyu Tan; Integrerade elektroniksystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; A D converters; CMOS circuit design; ΔΣ ADC; high-speed ADC; Nyquist-rate ADC; oversampled ADC; SAR ADC; 5G;

    Sammanfattning : The Analog to Digital (A/D) Converters (ADC) are vital components in high-performance radio devices. In the receiver end, the signal received by the analog front-end can not be directly analyzed by the digital core, thus requiring high-performance ADC circuits acting as bridges connecting the analog and digital domain.

  5. 29. Exploiting the Terahertz Spectrum with Silicon Micromachining : Waveguide Components, Systems and Metrology

    Författare :James Campion; Joachim Oberhammer; Umer Shah; Robert M. Weikle II; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Terahertz; Silicon Micromachining; Waveguide; Waveguide System; Metrology; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The terahertz spectrum (300 GHz - 3 THz) represents the final frontier for modern electronic and optical systems, wherein few low-cost, volume-manufacturable solutions exist. THz frequencies are of great scientific and commercial interest, with applications as diverse as radio astronomy, sensing and imaging and wireless communications. LÄS MER

  7. 30. Reduction of Substrate Noise in Mixed-Signal Circuits

    Författare :Erik Backenius; Mark Vesterbacka; Kejll O. Jeppson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mixed-signal; Substrate noise; Substrate modeling; Simultaneous switching noise; SSN; Digital; Analog; Clock; Electronics; Elektronik;

    Sammanfattning : In many consumer products, e.g., cellular phones and handheld computers, both digital and analog circuits are required. Nowadays, it is possible to implement a large subsystem or even a complete system, that earlier required several chips, on a single chip. LÄS MER
