  3. 2. System-on-package solutions for multi-band RF front end

    Författare :Xinzhong Duo; Li-Rong Zheng; Kari Halonen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chip-package co-design; multi-band radio; system-on-package; Electronic structure; Elektronstruktur;

    Sammanfattning : Advances in microelectronics technology have enabled us to integrate a complex electronic system (such as a radio) on a single chip or in a single package module, known as system-on-chip (SoC) and system-on-package (SoP) paradigms. This brings not only new opportunities for system integration, but also challenges in design and implementation. LÄS MER

  4. 3. Micro- and Millimeter Wave CMOS Beamforming Receivers

    Författare :Andreas Axholt; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; beamforming; CMOS; front-end; microwave; millimeter wave; phase-locked loop; phased-array;

    Sammanfattning : The available bandwidth in wireless communication systems, such as the 802.11 family, is very limited. Together with the ever increasing data traffic, this causes problems. New possibilities are, however, available thanks to wide license-free bandwidth allocated at higher frequencies. LÄS MER

  5. 4. Digitally controlled analog multiply-accumulate units

    Författare :Mattias Duppils; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis is about digitally controlled analog multiplier-accumulator (MAC) units and their utilization in communications applications. These units are implemented as switched-capacitor circuits, designed with switches (MOS transistors), capacitors (MOS transistors), and amplifiers (MOS transistors); using a CMOS technology. LÄS MER

  7. 5. 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.
