  1. 31. Toward Non-invasive Neonatal Gas Monitoring with Plasma-based Spectroscopy

    University essay from

    Author : Hedwig Haas; Hampus Fröjdholm; Carmen Lee; [2018]
    Keywords : plasma; sensor pad; transcutaneous; gas monitoring;

    Abstract : Transcutaneous gas monitoring of oxygen and carbon dioxide is animportant method for monitoring the oxygenation and ventilation inprematurely born infants. The amount of gas diffusing through theskin is very small and current technology rely on heating of theskin to increase the gas amount, where transcutaneous oxygenrequires the highest temperature.

  3. 32. 1kW Class-E solid state power amplifier for cyclotron RF-source

    University essay from Uppsala universitet/FREIA

    Author : Stefan Book; [2018]
    Keywords : Class-E; LDMOS; high efficiency; high power; VHF; power amplifier; accelerator; cyclotron;

    Abstract : This thesis discusses the design, construction and testing of a highefficiency, 100 MHz, 1 kW, Class-E solid state power amplifier. The design was performed with the aid of computer simulations using electronic design software (ADS). The amplifier was constructed around Ampleon's BLF188XR LDMOS transistor in a single ended design. READ MORE

  4. 33. 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.

  5. 34. An Energy Efficient Radio Base Station

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

    Author : Lakshmi Prasad; [2018]
    Keywords : Technology and Engineering;

    Abstract : The mobile telecommunication network is growing year after year and it will soon move into the high speed 5G and Internet of Things technology. These new technologies will improve the throughput and data connectivity and due to that the energy consumption in radio and digital units may increase in a Radio Base Station (RBS). READ MORE
