4. 2. Photonic Techniques for Real-Time Analog-to-Digital Conversion

   Author : Johan Stigwall; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tunable THz generation; photonic time-stretch; photonic sampling; Photonic analog-to-digital conversion; optical signal processin; photonic binary encoding; microwave photonics; photonic thresholding;

   Abstract : All-electronic analog-to-digital conversion (ADC) technology is limited by the timing accuracy and inherent speed of semiconductor materials. Photonic techniques, however, can potentially enable real-time ADC at a considerably wider bandwidth, higher sample rate and/or resolution, thanks to the availability of extremely accurate optical clocks and the immense bandwidth of optical systems.

5. 3. Modeling Analog to Digital Converters at Radio Frequency

   Author : Niclas Björsell; Peter Händel; Niclas Keskitalo; Linus Michaeli; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ADC; Analog to Digital Converters; Signal processing; Telecommunication; Telekommunikation; Electronics;

   Abstract : Det här arbetet handlar om att ta fram beteendemodeller av analog till digital omvandlare avsedda för tillämpningar i radiofrekvensområdet. Det gäller tillämpningar inom telekommunikation men även in test- och mätinstrument där omvandlingen från analoga till digitala signaler ofta är en prestandamässig flaskhals. READ MORE

6. 4. Characterization and Correction of Analog-to-Digital Converters

   Author : Henrik Lundin; Peter Händel; Mikael Skoglund; Paolo Carbone; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analog-to-digital converter; ADC; correction; post-correction; look-up table; characterization; calibration; Signal processing; Signalbehandling;

   Abstract : Denna avhandling behandlar analog-digitalomvandling. I synnerhet behandlas postkorrektion av analog-digitalomvandlare (A/D-omvandlare). A/D-omvandlare är i praktiken behäftade med vissa fel som i sin tur ger upphov till distorsion i omvandlarens utsignal. READ MORE

7. 5. Floating-Point Analog-to-Digital Converter

   Author : Johan Piper; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics and Electrical technology; matching; binary weighting; dynamic range; resolution; distortion; pipeline; A D-converter; floating-point; Elektronik och elektroteknik;

   Abstract : To deal with the wide dynamic rage necessary for a radio receiver or corresponding applications, but to avoid impractically high resolution at high data rates, the approach of using a floating-point analog-to-digital converter (FP-ADC) has been investigated. This approach de-links the dynamic range with the resolution, and a very wide dynamic range can be achieved by an ADC with a moderate resolution. READ MORE
