  1. 1. Estimating Ambient Temperature using Internal Sensors and Thermal Modelling in Mobile Phones

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Isak Evaldsson; Henrik Paulcén; [2023]
    Keywords : Technology and Engineering;

    Abstract : This thesis studies the possibility of estimating the ambient temperature around a mobile phone using its internal temperature sensors. The thesis aims to develop and evaluate ambient temperature models that use internal temperature sensors within the device and, from a manufacturer’s perspective, investigate if the models for ambient temperature can be enhanced by tailoring them to the internals of specific devices.

  2. 2. Design of a 13-Bit SAR ADC with kT/C noise cancellation technique

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

    Author : Shashank Keerthy Kumar; [2023]
    Keywords : Technology and Engineering;

    Abstract : One of the main limitations of a Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) is the large input capacitance needed to achieve the desired performance. This large input capacitance increases the total area of the ADC and it imposes the use of a powerful buffer to drive it. READ MORE

  3. 3. Evaluation of Discrete-Time Wideband Receivers for NB-IoT

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

    Author : Magnus Wasting; [2021]
    Keywords : Discrete; time; filter; NB-IoT; Charge; Sharing; CMOS; Technology and Engineering;

    Abstract : A receiver that covers several RF bands requires multiple front-end filters which increases the cost in terms of components and/or board/silicon area. Front-end filters assist a receiver to withstand interference at multiples of its down-conversion frequency. READ MORE

  4. 4. 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.

  5. 5. Hardware-software model co-simulation for GPU IP development

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

    Author : Jaime Gancedo Rodrigo; [2018]
    Keywords : Technology and Engineering;

    Abstract : This Master's thesis project aims to explore the possibility of a mixed simulation environment in which parts of a software model for emulating a hardware design may be swapped with their corresponding RTL description. More specifically, this work focuses on the sofware model for Arm's next-generation Mali GPU, which is used to understand system on chip properties, including functionality and performance. READ MORE
