1. 11. Design of VCO-based ADCs

   Författare :Vishnu Unnikrishnan; Mark Vesterbacka; Trond Ytterdal; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Today's complex electronic systems with billions of transistors on a single die are enabled by the aggressive scaling down of the device feature size at an exponential rate as predicted by the Moore's law. Digital circuits benefit from technology scaling to become faster, more energy efficient as well as more area efficient as the feature size is scaled down. LÄS MER

3. 12. Silicon Carbide Bipolar Integrated Circuits for High Temperature Applications

   Författare :Luigia Lanni; Carl-Mikael Zetterling; Niklas Rorsman; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Silicon carbide (SiC) is a semiconductor that provides significant advantages for high-power and high-temperature applications thanks to its wide bandgap, which is several times larger than silicon. The resulting high breakdown field, high thermal conductivity and high intrinsic temperature (well above 600 °C) allow high temperature operation of SiC devices and relaxed cooling requirements.

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

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

   Sammanfattning : 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. LÄS MER

5. 14. Distributed Clocking and Clock Generation in Digital CMOS SoC ASICs

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

   Sammanfattning : 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. LÄS MER

7. 15. Design and Security Analysis of TRNGs and PUFs

   Författare :Yang Yu; Elena Dubrova; Zhonghai Lu; Ilia Polian; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cryptographic primitive; Physical Unclonable Function; True Random Number Generator; Hardware security; Side-channel analysis; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : True Random Number Generators (TRNGs) and Physical Unclonable Functions (PUFs) are two important types of cryptographic primitives. TRNGs create a hardware-based, non-deterministic noise that is often used for generating keys, initialization vectors, and nonces for various applications that require cryptographic protection.
