2. 6. Receiver Front-Ends in CMOS with Ultra-Low Power Consumption

   Author : Carl Bryant; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; receiver; front-end; sensor networks; CMOS; ultra-low power; low noise amplifier; mixer; voltage-controlled oscillator; frequency divider; bluetooth;

   Abstract : Historically, research on radio communication has focused on improving range and data rate. In the last decade, however, there has been an increasing demand for low power and low cost radios that can provide connectivity with small devices around us. READ MORE

4. 7. Integrated Frequency Synthesis for Convergent Wireless Solutions

   Author : Jad G. Atallah; Mohammed Ismail Elnaggar; Erik Bruun; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless; transceiver; Bluetooth; DECT; GSM; 3G; LTE; WLAN; WiMAX; multi-standard; vertical handover; Sniffer; frequency synthesizer; phase-locked loop; PLL; sigma-delta; calibration; Electronics; Elektronik;

   Abstract : Wireless transceivers combining several standards in one unit are of key importance. In order to reach the ultimate goal of maximizing the performance-to-cost ratio of such modules, a careful study of the target application, the architecture, and the frequency planning is strongly required.

6. 9. Monolithic Integrated Oscillators - Phase Noise Analysis and Inductor Modeling

   Author : Niklas Troedsson; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; monolithic inductor; Monolithic integrated oscillator; CMOS; Bluetooth; low voltage; voltage controlled oscillator; Elektronik och elektroteknik; Electronics and Electrical technology; inductor modeling; phase noise analysis; quadrature voltage controlled oscillator;

   Abstract : This doctoral dissertation studies voltage controlled oscillators (VCOs) that operate at low supply voltages. Due to smaller transistor sizes and lower supply voltage ratings with every new CMOS technology, voltage headroom is diminishing. READ MORE

7. 10. Improved Performance of Bluetooth with Focus on Ad-Hoc Applications

   Author : Lennart Isaksson; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The number of devices making use of Bluetooth cable-replacement technology has rapidly increased in numbers thanks to the amount of implementations in cellular telephones, Personal Digital Assistants (PDAs), etc. Instead of the point-to-point technique used today the wireless community demands more sophisticated solutions to transmit information between two devices, e.
