1. 1. Development of a Hydraulic Front Wheel Drive for a Battery Electric Truck

   Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

   Författare :Johan Humla; Samuel Friman; [2023]
   Nyckelord :;

   Sammanfattning : This master thesis work has been executed at Volvo GTT in Gothenburg. Focus has beenlaid on implementing a hydraulic front wheel drive (HFWD) system on a battery electricvehicle (BEV). The earlier concept builds have been performed on internal combustionengine (ICE) driven trucks at Volvo Trucks. LÄS MER

3. 2. Temperature Compensation in CMOS Ring Oscillator

   Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

   Författare :Xiaohua Wei; Dingyufei Zhang; [2022]
   Nyckelord :Current Starved Ring Oscillator CSRO ; Temperature compensation; Supply voltage compensation; Stable frequency; Digital controlling; Phase Frequency Detector PFD ; Dynamic comparator; Bidirectional counter; Charge pump CP ; Frequency divider; Power consumption; AMS 0.35 um; EDA tool Cadence;

   Sammanfattning : A digital system is often required to operate under a specific frequency. A ring oscillator can be helpful in this circumstance because it can generate a signal with a specific frequency. However, a ring oscillator is also sensitive to the environment temperature. LÄS MER

4. 3. PLL for 5G mmWave

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

   Författare :Daniel Bakic; Jinzhuo Wu; [2020]
   Nyckelord :PLL; 5G-NR; RFIC; beamforming; 22nm FDSOI; charge pump; vco; loop filter; frequency divider; phase detector; phase noise; jitter; Technology and Engineering;

   Sammanfattning : This paper presents research and implementation of a high frequency Integer-N phase-locked loop for digital beamforming in mobile devices. Multiple topologies investigated whereof two were implemented. The transient phase noise of the PLL is -104dB/-95dB @1MHz. The output frequency range is from 8G-10G. LÄS MER

5. 4. Methodology For Improving performance & Reliability In Low Voltage on-chip Memories

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

   Författare :Hamed Movahedimeimandi; [2019]
   Nyckelord :Low power memories; Assist technique; Voltage Boosting; Charge pump; Sense amplifier; Voting method.; Technology and Engineering;

   Sammanfattning : Recent surveys show that on average about 70% of the area budget of the system on chip (SoC) is occupied by Static Random Access Memory (SRAM)s, with a capacity ranging from a few kilo-bits to tens of megabits. SRAM (static RAM or SRAM) is a type of electronic memory that uses bistable latching circuitry (flip-flop) to store each bit. LÄS MER

7. 5. Design of a 30 GHz PLL for use in Phased Arrays

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

   Författare :Byron Murphy; [2016]
   Nyckelord :pll; phase-locked loop; beamforming; vco; qvco; Technology and Engineering;

   Sammanfattning : This project includes the research and implementation of a high frequency phase-locked loop (30 GHz or more) for beamforming use in a phased antenna array. The phase-locked loop includes a quadrature voltagecontrolled oscillator with a 10% tuning range and 417 degrees of phase control with a 10 degree resolution, a current mode latch in the divide-bytwo configuration operates over the quadrature voltage-controlled oscillator’s tuning range while consuming less than 583 uA of current, Dtype flip flops in a divide-by-8 configuration, a phase-frequency detector, a charge-pump, and a loop filter.
