    Keywords : GMR; sensor; magnetic field; near-field; probe; linearity; PCB; coil; PCBA; analogue integrated circuits; analog; operational amplifiers; electrical fault detection; feedback circuits; in-circuit tests; GMR; sensor; magnetfält; närfält; sond; linjäritet; mönsterkort; spole; kretskort; analoga integrerade kretsar; operationsförstärkare; elektrisk feldetektering; återkopplingskretsar; kretskortstest;

    Abstract : 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. READ MORE

  3. 2. Methodology For Improving performance & Reliability In Low Voltage on-chip Memories

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

    Author : Hamed Movahedimeimandi; [2019]
    Keywords : Low power memories; Assist technique; Voltage Boosting; Charge pump; Sense amplifier; Voting method.; Technology and Engineering;

    Abstract : Recent surveys show that on average about 70% of the area budget of the system on chip (SoC) is occupied by Static Random Access Memory (SRAM)s, with a capacity ranging from a few kilo-bits to tens of megabits. SRAM (static RAM or SRAM) is a type of electronic memory that uses bistable latching circuitry (flip-flop) to store each bit. READ MORE

  4. 3. Characterization and Modeling of SiC Integrated Circuits for Harsh Environment

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Daiki Kimoto; [2017]
    Keywords : Silicon carbide; Harsh environment; High-temperature; Pseudo-CMOS; SPICE circuit simulation; Yield calculation; Silicon carbide; Extrema Miljöer; Hög tempeatur; Pseudo-CMOS; SPICE kretssimulering; Utbytet uträkning;

    Abstract : Elektronik för extrema miljöer, som kan användas vid hög temperatur, hög strålning och omgivning med frätande gaser, har varit starkt önskvärd vid utforskning av rymden och övervakning av kärnreaktorer. Kiselkarbid (SiC) är en av kandidaterna inom material för extrema miljöer på grund av sin höga temperatur- och höga strålnings-tolerans. READ MORE

  5. 4. Visual feedback to sonar clicks

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Fredrik Mårtensson; [2017]
    Keywords : Technology and Engineering;

    Abstract : The wildlife park Kolmården in Norrköping, Sweden, asked for a device that could visually feedback how dolphins use their ultrasound signals while echolocating objects. By recording the sound from the dolphin, process the sound and then create a visual feedback by having LED's flash in different frequencies, depending on the distance between dolphin and device.

  6. 5. Measurement of the convective heat transfer with wind : Developing and testing an Earth Scaled Atmospheric Temperature Sensor

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Philipp Wittmann; [2016]
    Keywords : Wind; ATS; heat transfer; air temperature sensor; atmospheric temperature sensor;

    Abstract :    The HAbitability, Brine Irradiation and Temperature Package (HABIT) instrument of the ExoMars Surface Platform will investigate the present day habitability of Mars at the near surface environment. This instrument includes three Atmospheric Temperature Sensor's (ATS's) which are similar to the ones previously used on the Rover Environmental Monitoring Station (REMS) of the Mars Science Laboratory (MSL) rover, that has now been operating on Mars for more than four years.
