1. 1. Charge Sampling Circuits and A/D Converters - Theory and Experiments

   Författare :Gang Xu; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pipelined A D converter; sigma-delta modulator; differential difference comparator; 2-step A D converter; FIR filter; analog filter; thermal noise; clock jitter; sub-sampling; RF sampling; current-mode sampling; Charge samling; A D converter; flexible A D converter; Electronics and Electrical technology; Elektronik och elektroteknik;

   Sammanfattning : The analysis of general charge sampling technique is presented in this thesis. Charge sampling integrates input current instead of tracking input voltage to realize high speed and low voltage sampling. The analysis focuses on the performance of general charge sampling circuits for signal capture. LÄS MER

3. 2. On small-signal analysis and control of the single- and the dual-active bridge topologies

   Författare :Georgios D. Demetriades; Hans-Peter Nee; Jorma Kyyrä; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; DC-DC converters; Soft-switching; High-frequency; High-power; Bi-directional; Single-Active Bridge; Elektronik; Electronics; Elektronik;

   Sammanfattning : High-frequency dc-dc converters are nowadays widely used in a diversity of power electronic applications. High operating frequencies entail a reduction in size of the passive components, such as inductors, capacitors and power transformers. LÄS MER

4. 3. Equalization of Distortion in A/D Converters

   Författare :Jonas Elbornsson; Fredrik Gustafsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Modern communication systems require A/D converters with very high sample rate and high accuracy. CMOS technology is suitable for integrating A/D converters on a chip at a low cost and low power consumption. However, the CMOS manufacturing process is quite inaccurate, which leads to errors in the A/D converters. LÄS MER

7. 5. Analysis, Estimation and Compensation of Mismatch Effects in A/D Converters

   Författare :Jonas Elbornsson; Fredrik Gustafsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; A D converter;

   Sammanfattning : The trend in modern communication systems is to replace as much analog circuits as possible with digital ones, to decrease size, energy consumption and cost. An analog to digital converter (ADC) is the interface between the analog and digital parts. Replacing analog parts, such as mixers, with digital ones requires higher sampling rates. LÄS MER
