    Sammanfattning : As electronics are getting both smaller and more advanced, the need to verify and validate remains and the means are getting more complex the more functions and components are added. Traditionally, in-circuit tests (ICTs) are performed by probing dedicated test points on the Printed Circuit Board Assembly (PCBA) in a test sequence that is unique to each product. LÄS MER

  2. 2. Current sensing in software for electronic fuse applications : Analysis of two different current measurement implementations

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Nyckelord :Electronic fuse; Current sensing; Sensors; Microcontroller; Shunt resistor; Elektronisk säkring; Strömmätning; Sensorer; Mikrokontroller; Strömavkänningsmotstånd;

    Sammanfattning : Relays and fuses are used in a multitude of applications to deliver and control current to its consumers. To improve the controllability of both the fuse and relay function, they can be moved to software. This will not only increase the number of available features but can also give live feedback of the systems current state. LÄS MER

  3. 3. Capacitance Optimization and Ballistic Modeling of Nanowire Transistors

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Azal Alothmani; [2018]
    Nyckelord :Nanowire transistor; 1-D MOSFET; RF performance; permittivity; parasitic capacitance; HSQ; COMSOL Multiphysics; Technology and Engineering;

    Sammanfattning : Downscaling of Si-based metal-oxide-semiconductor field-effect transistors (MOSFETs) has contributed to increased microchip device density and to improve the functionality of the electronic circuits. The dimensions of state of art MOSFET is down to a few nanometers. It has been demonstrated that smaller MOSFETs are faster and more energy-efficient. LÄS MER

  4. 4. Modelling and Analysis of Substrate Noise in Delta Sigma ADCs

    Sammanfattning : The rapid development in the semiconductors industry has enabled the placement of multiple chips on a single die. This has helped boost the functionality of modernday application specific integrated circuits (ASICs). Thus, digital circuits are being increasingly placed along-side analog and RF circuits in what are known as mixed signal circuits. LÄS MER

  5. 5. Integrering av luftfuktighetssensor

    Kandidat-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Emanoel Tanzi; Milenko Ilic; [2017]
    Nyckelord :;

    Sammanfattning : In this project a humidity sensor will be integrated to measure humidity. There are several different methods for integrating a humidity sensor but for this project two models will be used to integrate the sensor and compare with the theory. The construction of the two models are in KiCad and then it will be ordered as PCBs. LÄS MER
