3. 2. Design and Implementation of Sigma-Delta Converter : in Oversampling frequency

   Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Författare :Yaobin Pan; Xizhuo Li; [2016]
   Nyckelord :Sigma-Delta converters; Oversampling; Analog-Digital converters;

   Sammanfattning : Nowadays, Sigma-Delta analog-to-digital converters have been widely used in the technology of analog-to-digital conversion. It depends on the merits that the approach of Sigma-Delta has. The signal converted by oversampling is precise and well-suited in signal processing systems. LÄS MER

4. 3. System Level Modeling and Verification of All-digital Phase-locked Loop

   Kandidat-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Författare :Chi Zhang; [2015]
   Nyckelord :;

   Sammanfattning : In wirelesscommunication systems, a local oscillator (LO) aims at demodulating radio-frequency signals into baseband signals. The performance of these signals determines the quality of communications which is highly affected by the phase accuracy of local oscillators. LÄS MER

5. 4. All-Digital ADC Design in 65 nm CMOS Technology

   Master-uppsats, Linköpings universitet/Elektroniksystem; Linköpings universitet/Tekniska högskolan

   Författare :Srinivasa Rao Pathapati; [2014]
   Nyckelord :Digital ADC; TDC; VCO-based ADC; VCO-based quantizer;

   Sammanfattning : The design of analog and complex mixed-signal circuits in a deep submicron CMOS process technology is a big challenge. This makes it desirable to shift data converter design towards the digital domain. LÄS MER

7. 5. The design of an all-digital VCO-based ADC in a 65nm CMOS technology

   Master-uppsats, Linköpings universitet/Elektroniksystem; Linköpings universitet/Tekniska högskolan

   Författare :Manivannan Thangamani; Allen Arun Prabaharan; [2014]
   Nyckelord :VCO-ADC; VCO-bsaed ADC; Time-based quantizer; all-digital ADC; VCO; FDC;

   Sammanfattning : This thesis explores the study and design of an all-digital VCO-based ADC in a 65 nm CMOS technology. As the CMOS process enters the deep submicron region, the voltage-domain-based ADCs begins to suffer in improving their performance due to the use of complex analog components. LÄS MER
