1. 1. Low-Power Low-Jitter Clock Generation and Distribution

   Författare :Behzad Mesgarzadeh; Atila Alvandpour; Thucydides Xanthopoulos; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-power; resonant clock distribution; injection locking; DLL-based clock generation; jitter suppression; CMOS; Electronics; Elektronik;

   Sammanfattning : Today’s microprocessors with millions of transistors perform high-complexitycomputing at multi-gigahertz clock frequencies. Clock generation and clockdistribution are crucial tasks which determine the overall performance of amicroprocessor. LÄS MER

3. 2. 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

4. 3. Timing Uncertainty in Sigma-Delta Analog-to-Digital Converters

   Författare :Adam Strak; Hannu Tenhunen; Franco Maloberti; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; timing uncertainty; clock jitter; Sigma-Delta Analog-to-Digital Converter; sampling; clock generation; power-supply noise; substrate noise; Electronics; Elektronik;

   Sammanfattning : Denna avhandling presenterar en undersökning av orsakerna och effekterna av timingosäkerhet i Sigma-Delta Analog-Digital-Omvandlare, med speciellt fokus på Sigma-Delta av den switchade kapacitanstypen. Det undersökta området för orsakerna till timingosäkerhet är digital klockgenerering och området för effekterna är sampling. LÄS MER

5. 4. Contributions to Asynchronous Communication Ports for GALS Systems

   Författare :Jonas Carlsson; Juha Plosila; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GALS; Asynchronous; Asynchronous communication ports; Clock gating; Clock domains; Electronics; Elektronik;

   Sammanfattning : Digital systems commonly use a single global clock signal to synchronize the whole system. This is not always possible and it can be more advantageously to divide the system into separate clock domains, where each clock domain can operate with its own clock frequency. LÄS MER

7. 5. Power Estimation and Multi-Phase Clock Generation for the Deep Submicron Era

   Författare :Daniel Eckerbert; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Scaling has been the driving force behind the immense development the field of electronics has seen over the last few decades. It has brought us from integrated circuits operating in the kilohertz range in the 1970s to the gigahertz range in just thirty years. LÄS MER
