   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Joacim Sundh; [2022]
   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. 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.

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

   University essay from Uppsala universitet/Elektricitetslära

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

   Abstract : 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. READ MORE

5. 4. 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
