1. 16. Design of a 30 GHz PLL for use in Phased Arrays

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

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

   Abstract : 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.

3. 17. 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

4. 18. Inkjet deposition of electrolyte : Towards Fully Printed Light-emitting Electrochemical Cells

   University essay from Umeå universitet/Institutionen för fysik

   Author : Mattias Lindh; [2013]
   Keywords : inkjet printing; organic electronics; light-emitting electrochemical cell; solid electrolyte; coffee ring; stone ship; wettability; bläckstråleskrivare; organisk elektronik; ljusemitterande elektrokemiska celler; fast elektrolyt; kaffering; skeppssättning; vätbarhet;

   Abstract : Organic electronics is a hot and modern topic which holds great promise for present and future applications. One such application is the light-emitting electrochemical cell (LEC). It can be fully solution processed and driven at low voltage providing light emission from a large surface. READ MORE

5. 19. Modeling of an IGBT and a Gate Unit

   University essay from KTH/Elektrisk energiomvandling

   Author : Henrik Hollander; [2013]
   Keywords : IGBT model; Behavioral model; Single Pulse Test Circuit; Gate Unit model;

   Abstract : The purpose of this master thesis was to create a model of an IGBT in a single pulse test circuit and connect this model to a model of a Gate Unit. The IGBT model and the single pulse test circuit were both implemented in MATLAB and the Gate Unit was implemented in Simulink. READ MORE

6. 20. Optimized Tuning of Parameters for HVDC Dynamic Performance Studies

   University essay from Institutionen för informationsteknologi

   Author : Axel Andersson; [2013]
   Keywords : optimization;

   Abstract : HVDC (High Voltage Direct Current) is used all over the world for transmission of electric power due to lower losses compared to traditional HVAC (High Voltage Alternating Current). However, the procedure of converting AC into DC puts great demand on the control system of the converter stations. READ MORE
