1. 11. Modeling and post-correction of pipeline analog-digital converters

   Författare :Samer Medawar; Peter Händel; Martin Gustafsson; KTH; []
   Nyckelord :;

   Sammanfattning : Integral nonlinearity (INL) for pipelined analog-digital converters (ADCs) operating at radio frequency is measured and characterized. A parametric model for the INL of pipelined ADCs is proposed and the corresponding least-squares problem is formulated and solved. LÄS MER

3. 12. Power-Efficient Continuous-Time Incremental Sigma-Delta Analog-to-Digital Converters

   Författare :Sha Tao; Ana Rusu; Franco Maloberti; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analog-to-digital conversion; sigma-delta modulation; incre- mental ADC; two-step ADC; continuous-time; biosensor applications.;

   Sammanfattning : Over the past decade, there has been a growing interest in the devel- opment of integrated circuits (ICs) for wearable or implantable biosensors, aiming at providing personalized healthcare services and reducing the health-care expenses. In biosensor ICs, the analog-to-digital converter (ADC) is a key building block that acts as a bridge between analog signals and digital processors. LÄS MER

4. 13. High-Speed Analog-to-Digital Converters in CMOS

   Författare :Siyu Tan; Integrerade elektroniksystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; A D converters; CMOS circuit design; ΔΣ ADC; high-speed ADC; Nyquist-rate ADC; oversampled ADC; SAR ADC; 5G;

   Sammanfattning : The Analog to Digital (A/D) Converters (ADC) are vital components in high-performance radio devices. In the receiver end, the signal received by the analog front-end can not be directly analyzed by the digital core, thus requiring high-performance ADC circuits acting as bridges connecting the analog and digital domain.

5. 14. Design of High-Speed Analog-to-Digital Converters using Low-Accuracy Components

   Författare :Timmy Sundström; Atila Alvandpour; Jan-Erik Eklund; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The scaling of CMOS technologies has increased the performance of general purpose processors and DSPs. However, analog circuits designed in the same process have not been able to utilize the scaling to the same extent, suffering from reduced voltage headroom and reduced analog gain. LÄS MER

7. 15. Design of Ultra-Low-Power Analog-to-Digital Converters

   Författare :Dai Zhang; Atila Alvandpour; Trond Ytterdal; Linköpings universitet; []
   Nyckelord :analog-to-digital converter; ADC; successive approximation register; SAR; SAR ADC; ultra-low-power; power consumption bounds; medical implant devices;

   Sammanfattning : Power consumption is one of the main design constraints in today’s integrated circuits. For systems powered by small non-rechargeable batteries over their entire lifetime, such as medical implant devices, ultra-low power consumption is paramount. LÄS MER
