   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Martin Alumets; Mattias Evaldsson; [2021]
   Keywords : Technology and Engineering;

   Abstract : Radar systems have been around since the early 20th century, and technology is advancing at an ever-increasing speed. This has led to great achievements in radar development, which have expanded the technology's area of use. READ MORE

3. 2. A Quadrature Frequency Generation Chain for Direct-conversion Phased-array 5G Transceivers

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Hamid Yadegar Amin; [2020]
   Keywords : 5G Phased array mm-wave FR2; Technology and Engineering;

   Abstract : The 5th generation (5G) has recently specified a new spectrum range, FR2- 5G New Radio (5G-NR), to provide higher spectral efficiency and channel capacity for ubiquitous cellular connectivity where the user ends can be in various types such as picocell stations, sensor nodes, cloud servers, hand-held devices, and so on. Due to the advantage of phased array antennas in performing beam-forming, and improving SNR at higher spectra, multi-antenna systems have gained an inevitable role in developing such radios.

4. 3. PLL for 5G mmWave

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

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

   Abstract : 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. READ MORE

5. 4. Phase Locked Loops in Fully Integrated NB-IoT Transceivers

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Adam Waks; [2018]
   Keywords : Phase locked loops; Narrow Band Internet of Things; Frequency pulling; Balun; Inductor; Technology and Engineering;

   Abstract : This thesis investigates how to fulfill the Narrow Band - Internet of Things (NB-IoT) specification for a fully integrated transceiver in the phase locked loop's (PLL) perspective. Designing a fully integrated transceiver, integrating a power amplifier (PA) is challenging as it leads to frequency pulling of the voltage controlled oscillator (VCO) in the PLL, deteriorating the performance.

6. 5. DLL Based Reference Multiplier for the use in a PLL for WLAN applications

   University essay from Lunds universitet/Fysiska institutionen

   Author : Kamal Gupta; [2015]
   Keywords : reference multiplier; Frequency synthesizer; Frequency multiplier; PLL; DLL; Delay locked loop; VCDL; inverter-based VCDL; charge pump; XOR phase detector; phase noise; 4X multiplier; Technology and Engineering;

   Abstract : This master’s thesis project report deals with the design of multiplier for the reference signal to the Phase Locked Loop (PLL) used in WLAN application. The reference multiplier designed is based on a newly proposed architecture of dual loop feedback Delay Locked Loop (DLL) in which multiplication is performed within the loops. READ MORE
