  2. 1. Distributed Clocking and Clock Generation in Digital CMOS SoC ASICs

    Author : Thomas Olsson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik; dual supply voltage; clock generator; digital; VHDL; CMOS; low-power; Distributed clocking; PLL;

    Abstract : With shrinking technologies and higher clock rates comes the possibility to transform multi chip implementations to a single System on Chip (SoC). Implementing clock distribution and limiting the power consumption becomes increasingly troublesome with increased clock rate and chip area. READ MORE

  4. 2. On LFSR based Stream Ciphers - analysis and design

    Author : Patrik Ekdahl; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; self-shrinking generator; shrinking generator; E0; A5; sober; stream cipher; LFSR; snow; Informatics; systems theory; Informatik; systemteori;

    Abstract : Stream ciphers are cryptographic primitives used to ensure privacy in digital communication. In this thesis we focus on stream ciphers built using Linear Feedback Shift Registers (LFSRs). Several different stream ciphers are analysed and new attacks are presented. In addition, two new stream ciphers are presented, both based on the same design. READ MORE

  5. 3. Radio and Sensor Interfaces for Energy-autonomous Wireless Sensing

    Author : Jia Mao; Lirong Zheng; Zhuo Zou; Markku Åberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultra-wideband; asymmetric UHF UWB radio; clock harvesting; time-domain sensing; energy efficiency; Internet-of-things; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Along with rapid development of sensing and communication technology, Internet of Things (IoTs) has enabled a tremendous number of applications in health care, agriculture, and industry. As the fundamental element, the wireless sensing node, such as radio tags need to be operating under micro power level for energy autonomy. READ MORE

  6. 4. Custom Designed Digital Signal Processors Using Bit-Serial Arithmetic

    Author : Peter Nilsson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; On-Chip Clocking; Digital IF-Filtering; Digital Wideband Filtering; Elektronik; Electronics; Bit-Serial Arithmetic; CMOS; Custom DSP; VLSI;

    Abstract : This thesis presents two prime contributions. First, digital filters for both intermediate and base band filtering for mobile communication are presented. Second, a local clock for on-chip clock generation is introduced. The intermediate frequency filter is a digital alternative to today's analog filters. READ MORE
