1. 1. Ring amplifiers for high speed pipeline assisted SAR ADCs

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Johan Holmstedt; [2020]
   Nyckelord :ADC SAR RAMP ring amp residue amplifier PVT; Technology and Engineering;

   Sammanfattning : This thesis contains a review of published ring amplifier topologies. It is suggested to split the input stage of the ring amplifier into two. In this way, a robust ring amplifier can be designed without stacking the transistors in the second stage of the ring amplifier, boosting its speed properties. LÄS MER

3. 2. Digitally Controlled Oscillator for mm-Wave Frequencies

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Rikard Gannedahl; Johan Holmstedt; [2018]
   Nyckelord :RF; RFIC; oscillator; DCO; mm-wave; Technology and Engineering;

   Sammanfattning : In the fifth generation of mobile communication, 5G, frequencies above 30 GHz, so-called millimeter-wave (mm-wave) frequencies are expected to play a prominent role. For the synthesis of these frequencies, the all-digital phase locked loop (ADPLL) has recently gained much attention. LÄS MER
