1. 41. Electrical Pulsing of a Laser Diode for Usage in Fluorescence Microscopy

   University essay from Linköpings universitet/Elektroniska Kretsar och System

   Author : Karin Jerner; [2017]
   Keywords : electrical pulsing; laser pulsing; fluorescence microscope; laser diode;

   Abstract : A relatively new application for the laser is in fluorescence microscopes. The fluo- rescence microscope needs a high power light source input. Using a laser source improves the precision of the microscope. A pulsed laser source enhances the performance of the fluorescence microscope and a laser diode can be overdriven without being damaged.

3. 42. Development of a Class D motor amplifier for a next-generation mechanism control electronics

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Juan Camilo Garcia Hernandez; [2016]
   Keywords : Power; electronics; satellites; BLDC; sinusoidal; commutation; control; PID; class D amplifier; PWM;

   Abstract : This thesis was written at Airbus DS GmbH in Friedrichshafen, Germany, as part of a project which aims to develop a new generation of class-D power amplification circuits for sinusoidal commutating motors controlling the movement of different mechanisms in satellites. Currently used topologies have disadvantages such as high power loss, analog controlling and high degree of signal distortion. READ MORE

4. 43. Integrated CMOS Doppler Radar : Power Amplifier Mixer

   University essay from Linköpings universitet/Elektroniska Kretsar och System

   Author : Olof Sjöholm; [2016]
   Keywords : Doppler Radar Power Amplifier Mixer CMOS RF;

   Abstract : This thesis is based on a paper by V. Issakov, presented 2009, where a circuit of a merged power amplifier mixer solution was demonstrated. This work takes that solution and simplifies it for the use at a lower frequency. The implementation target is a Doppler radar application in CMOS that can detect humans in a range of 5 to 15 meters.

5. 44. Behavioral Modeling of Power Amplifier with Memory Effect and Linearization Using Digital Pre Distortion

   University essay from Högskolan i Gävle/Elektronik

   Author : Om Prakash Nandi; [2016]
   Keywords : Behavioral Modeling; Power Amplifier; DPD;

   Abstract : This thesis work studied the behavioral modeling, estimation of parameters, model performance and linearization of power amplifier (PA) using Digital Pre Distortion (DPD) technique. PAs are one of the fundamental block in communication systems and also one of the main sources of nonlinearities in the system, as these devices are frequently subjected to signals characterized by considerable bandwidths and non-constant envelopes due to use of modern modulation technique.

6. 45. Understanding the Parasitic Effects on the Microwave Interferences at Hearing Instrument Level up to 6GHz

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

   Author : Thomas Sofya; [2016]
   Keywords : Technology and Engineering;

   Abstract : The use of electronic devices which radiate high power electromagnetic waves has seen a significant increase in the last 20 years. These radiated signals heavily effects electronic devices close to strong radio frequency (RF) or microwave (MW) transmitters . READ MORE
