4. 13. Receiver Front-end Design for WiMAX/LTE in 90 nm CMOS

   Uppsats för yrkesexamina på avancerad nivå,

   Författare :Hans Rabén; [2009]
   Nyckelord :;

   Sammanfattning : The development of wireless communication systems into multi-standard radio architectures that can process a multitude of frequency bands and modulation schemes has lead to a growing demand for wideband receiver front-ends. To allow for portability and low cost, these new architectures also need to be low power, compact size integrated circuits with a higher degree of components integrated on chip. LÄS MER

5. 14. Design and Evaluation of A Low-Voltage, Process-Variation-Tolerant SRAM Cache in 90nm CMOS Technology

   Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

   Författare :Ali Fazli Yeknami; [2008]
   Nyckelord :SRAM; traditional 6T; asymmetric 6T; memory; SNM; cell;

   Sammanfattning : This thesis presents a novel six-transistor SRAM intended for advanced microprocessor cache application. The objectives are to reduce power consumption through scaling the supply voltage and to design a SRAM that is fully process-variation-tolerant, utilizing separate read and write access ports as well as exploiting asymmetry.

7. 15. A High Speed Sigma Delta A/D-Converter for a General Purpose RF Front End in 90nm-Technology

   Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

   Författare :Per Öresjö; [2007]
   Nyckelord :ADC; A D Converter; analog-to-digital converter; Sigma Delta;

   Sammanfattning : In this report a transistor-level design of a GHz Sigma-Delta analog-to-digital converter for an RF front end is proposed. The design is current driven, where the integration is done directly over two capacitances and it contains no operational amplifiers. The clock frequency used for verification was 2.5 GHz and the output band-width was 10 MHz. LÄS MER
