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. 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

4. 3. 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

5. 4. Reduction of Substrate Noise in Mixed-Signal Circuits

   Författare :Erik Backenius; Mark Vesterbacka; Kejll O. Jeppson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mixed-signal; Substrate noise; Substrate modeling; Simultaneous switching noise; SSN; Digital; Analog; Clock; Electronics; Elektronik;

   Sammanfattning : In many consumer products, e.g., cellular phones and handheld computers, both digital and analog circuits are required. Nowadays, it is possible to implement a large subsystem or even a complete system, that earlier required several chips, on a single chip. LÄS MER

7. 5. On Reduction of Substrate Noise in Mixed-Signal Circuits
