1. Distributed Clocking and Clock Generation in Digital CMOS SoC ASICs
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
2. On LFSR based Stream Ciphers - analysis and design
Sammanfattning : 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. LÄS MER
3. Radio and Sensor Interfaces for Energy-autonomous Wireless Sensing
Sammanfattning : 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. LÄS MER
4. Custom Designed Digital Signal Processors Using Bit-Serial Arithmetic
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. Circuit Techniques for On-Chip Clocking and Synchronization
Sammanfattning : Today’s microprocessors with millions of transistors perform high-complexity computing at multi-gigahertz clock frequencies. The ever-increasing chip size and speed call for new methodologies in clock distribution network. LÄS MER
