2. 1. Continuous-Time Delta-Sigma Modulators for Wireless Communication

   Author : Mattias Andersson; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; return-to-zero; A D converter; loop delay; delta-sigma; ADC; CMOS; STF; continuous-time; sigma; delta; filtering; CT; RZ;

   Abstract : The ever increasing data rates in wireless communication require analog to digital converters (ADCs) with greater requirements on speed and accuracy, while being power efficient to prolong battery life. This dissertation contains an introduction to the field and five papers that focus on the continuous-time (CT) Delta-Sigma modulator (DSM) as ADC. READ MORE

4. 2. Continuous-Time Delta-Sigma Modulators for Ultra-Low-Power Radios

   Author : Dejan Radjen; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Delta-Sigma; continuous-time; analog-to-digital; ultra-low-power; clock jitter; single operational amplifier; SAR quantizer;

   Abstract : The modern small devices of today require cheap low power radio frequency (RF) transceivers that can provide reliable connectivity at all times. In an RF transceiver, the analog-to-digital converter (ADC) is one of the most important parts and it is also one of the main power consumers. READ MORE

5. 3. Sensor Fusion and Control Applied to Industrial Manipulators

   Author : Patrik Axelsson; Mikael Norrlöf; Fredrik Gustafsson; Paolo Rocco; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Robots; Sensor Fusion; Iterative Learning Control; H-infinity Controller; Controllability; Extended Kalman Filter; Particle Filter; Expectation Maximisation; Continuous-time Filtering; Norm-optimal ILC;

   Abstract : One of the main tasks for an industrial robot is to move the end-effector in a predefined path with a specified velocity and acceleration. Different applications have different requirements of the performance. READ MORE

6. 4. Wideband Sigma-Delta Modulators

   Author : Xiaolong Yuan; Svante Signell; Jakob Wikner; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sigma-delta modulator; feedforward; reconfigurable; quadrature bandpass filtering; Electronics; Elektronik;

   Abstract : Sigma-delta modulators (SDM) have come up as an attractive candidatefor analog-to-digital conversion in single chip front ends thanks to the continuousimproving performance. The major disadvantage is the limited bandwidthdue to the need of oversampling. READ MORE

7. 5. On Modeling and Control of Network Queue Dynamics

   Author : Frida Gunnarsson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network flow control; Queue management;

   Abstract : Internet flow control algorithms used today are separately designed and tuned for outdated setups and traffic mixes. Differnet algorithms exist in both end nodes an core routers of a network. This work presents improved techniques for network flow control. READ MORE
