   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

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

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

   Författare :Shen Zhang; [2021]
   Nyckelord :Technology and Engineering;

   Sammanfattning : 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. 3. EMC Test Equipment for 5G at Ericsson : Recomission and optimisation of test equipment for radiated immunity 1-10 GHz

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

   Författare :Oliver Djurle; [2020]
   Nyckelord :5G; internet; network; electromagnetic compatibility; EMC; radiated immunity; test; standard; equipment;

   Sammanfattning : As demand for 5G networks increase, so does the development of network products. In-house testing is essential during the development stage as it enables faster product releases. A part of in-house testing is the product verification stage that includes electromagnetic compatibility (EMC) tests. LÄS MER

5. 4. Methodology For Improving performance & Reliability In Low Voltage on-chip Memories

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

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

   Sammanfattning : 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. LÄS MER

7. 5. Development of a Simple and Cheap Equipment for monitoring the solar Irradiance on PV modules.

   Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

   Författare :Pablo Casanaba; [2019]
   Nyckelord :Photovoltaic; DC; DAQ system; photocurrent; operational amplifier; pyranometer; reference solar cell; photodiode; irradiance;

   Sammanfattning : Increased use of renewable energies that is taking place all over the world is having a very important impact on the photovoltaic solar energy industry. This means of obtaining electrical energy is one of the most promising ones nowadays, thanks to the fact that it is a technology of easy installation and maintenance. LÄS MER
