  1. 16. Methods of self-interference cancellation in full duplex telecommunication systems

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Henrik Erlandsson; Viktor Sköldheden; [2021]
    Keywords : telecommunication; full duplex; self-interference cancellation; electronics; wireless communication; power amplifier;

    Abstract : With the wireless technology evolving quickly, so does the demand of speed and efficiency. This makes the companies look for new and better ways to improve the current systems. One way of improving the present systems would be to employ Full Duplex Technology. READ MORE

  3. 17. A design of a 100 MS/s, 8-bit Pipelined ADC in CMOS

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

    Author : Shen Zhang; [2021]
    Keywords : Technology and Engineering;

    Abstract : The thesis focuses on designing and simulating an 8-bit high-speed fully differential pipelined Analog to Digital Converter (ADC) in the 65nm Complementary Metal-Oxide-Semiconductor (CMOS) technology by using the software Cadence Virtuoso. The aim is to increase the operation speed of the ADC for communication systems without reducing the performance, in the meantime, the low power consumption and the low complexity should also be required when considering future implementation.

  4. 18. Current Control and Modelling of an Inspiration Valve

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Astrid Lindstedt; [2021]
    Keywords : Current Servo; Cascade Control; Solenoid Model; Ventilator; Strömregulator; Kaskadreglering; Solenoid modell; Respirator;

    Abstract : An analog current servo of an intensive care ventilator is being developed at Getinge in Stockholm. The current servo is used to control the output gas flow of an inspiration valve to a patient’s lungs. The ventilator’s control system is in a cascade design of two closed-loops, of which the current servo is the controller for the inner loop. READ MORE

  5. 19. Direct Sampling of the Pulsed Eddy Current Response From Non-Ferromagnetic Metals

    University essay from Umeå universitet/Institutionen för fysik

    Author : Sara Holmér; [2021]
    Keywords : ;

    Abstract : The non-destructive testing method Pulsed Eddy Current, or PEC, can be used to measure the thickness and resistivity of conducting and non-ferromagnetic materials. In this project I investigated if a gauge at ABB, which uses PEC technology to measure the thickness of aluminium strips in rolling mills, can extract more information about the strip by sampling the direct signal with a higher resolution than before.

  6. 20. Linearization of Resistive Digital-to-Analog Converter for RF-Applications Using Compensator and Digital Predistortion

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Henrik Eklund; [2021]
    Keywords : DAC; RDAC; DPD; Linearization; Digital-to-Analog Converter; Resistive Digital-to-Analog Converter; Digital Predistortion;

    Abstract : High-speed digital-to-analog converters are critical components in many radiofrequency (RF) applications. The resistive DAC (RDAC) architecture is suitable for high-speed implementation in extremely scaled digital circuit nodes. READ MORE
