1. 1. Analogue Circuit for Detection of Ageing Phenomena in Electric Drives

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

   Författare :Yudong Lin; [2023]
   Nyckelord :Electric Drives; Ageing Process; Pulse-Width Modulation; Ringing Current; Peak Holder; Analogue Circuits; Elektriska drivsystem; Åldringsprocess; Pulsbreddsmodulering; Ringningar i strömmen; Toppvärdesdetektor; Analog krets;

   Sammanfattning : This master thesis presents an analogue peak holder circuit design aimed at facilitating the non-invasive inspection of the ageing process in electric drives. The ageing process of electric drives is a crucial aspect that demands accurate monitoring to ensure their long-term performance and reliability. LÄS MER

3. 2. Circuit design and hardware implementation of an analog synthesizer

   Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

   Författare :Olle Murhed; [2023]
   Nyckelord :synthesizer; analogue; circuit design; sound; sound synthesis; oscillator; VCO; filter; amplifier; sequencer; control voltage; breadboard;

   Sammanfattning : Since the heyday of analogue synthesizers in the 70's, they have largely been replaced by digital hardware and software synthesizers. However, in recent years, there has been a revival in analogue designs, possibly due to its ``warmer" sound. LÄS MER

4. 3. 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)

   Författare :Joacim Sundh; [2022]
   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

5. 4. 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.

7. 5. Development of a Class D motor amplifier for a next-generation mechanism control electronics

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Juan Camilo Garcia Hernandez; [2016]
   Nyckelord :Power; electronics; satellites; BLDC; sinusoidal; commutation; control; PID; class D amplifier; PWM;

   Sammanfattning : This thesis was written at Airbus DS GmbH in Friedrichshafen, Germany, as part of a project which aims to develop a new generation of class-D power amplification circuits for sinusoidal commutating motors controlling the movement of different mechanisms in satellites. Currently used topologies have disadvantages such as high power loss, analog controlling and high degree of signal distortion. LÄS MER
