1. 11. Wave Propagation Experiment on FPGA with Miniaturized Payload for Sounding Rocket Application

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

   Författare :Leonardo Filippeschi; [2022]
   Nyckelord :Wave propagation experiment; REXUS BEXUS; FPGA; IQ demodulation; ADC; VHDL;

   Sammanfattning : This bachelor's thesis aims to implement a wave propagation experiment on Field-Programmable Gate Array to detect the signal strength at pre-defined frequencies for use in sounding rocket experiments. This includes the choice of suitable components such as analog to digital converters, filters, voltage regulators, and amplifiers. LÄS MER

3. 12. Towards a Cooper pair splitter in InAs nanowires with crystal-phase defined quantum dots

   Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Lunds Tekniska Högskola

   Författare :Louise Olausson; [2022]
   Nyckelord :Cooper pair splitter; quantum dot; nanowire; superconductivity; InAs; crystal-phase; Physics and Astronomy;

   Sammanfattning : Cooper pair splitting (CPS) is a process in which the two spin-entangled electrons of a Cooper pair in a superconductor are split into two spatially separated electrons. If the separated electrons are still entangled, CPS can be studied to increase the knowledge of non-locality in quantum systems. LÄS MER

4. 13. PCBA verification and fault detection using a low-frequency GMR-based near-field probe with magnetic closed-loop feedback compensation : A non-contact alternative to physical probing

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

   Nyckelord :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;

   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

   Sammanfattning : Two different topologies of power amplifiers (PAs) are designed in the frequency range 130-174.8 GHz for use in backhaul transmitters. These are the pseudo-differential common source (PDCS) and the single-ended stacked amplifier topologies. LÄS MER

7. 15. Niobium Ohmic Contacts for Cryogenic Indium Phosphide High-Electron-Mobility Transistors

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Linnéa Bendrot; [2022]
   Nyckelord :Ohmic contacts; high-electron-mobility transistor; InP; Nb films; cryogenic electronics; low-noise amplifier; quantum computing; transfer length method; superconductivity; contact barrier resistance; Ohmska kontakter; högelektronmobilitetstransistorer; indiumfosfid; niob; tunnfilm; kryogen elektronik; lågbrusförstärkare; kvantdatorer; Transfer Length-metod; supraledning; kontakt- barriärresistans;

   Sammanfattning : Ohmic contacts are crucial components in semiconductor devices such as transistors and diodes, and lowering their contact resistance is an important factor in device performance enhancement. This is especially important for low-noise amplifiers (LNAs) where device noise temperature decreases both directly and indirectly with decreasing contact resistance. LÄS MER
