  1. 21. Simulation of Temperature Distribution in IR Camera Chip

    Uppsats för yrkesexamina på avancerad nivå, Informationskodning

    Författare :Stefan Salomonsson; [2011]
    Nyckelord :Thermal modeling; Thermal imaging; Bolometer detector; Finite Element Method; COMSOL Multiphysics;

    Sammanfattning : The thesis investigates the temperature distribution in the chip of an infrared camera caused by its read out integrated circuit. The heat from the read out circuits can cause distortions to the thermal image. LÄS MER

  3. 22. Implementation of Low Power, Wide Range ADPLL for Video Applications

    Master-uppsats, Elektroniksystem

    Författare :Abdul Raheem Qureshi; Haris Qazi; [2010]
    Nyckelord :PLL; Digital; Low Power; Wide Range;

    Sammanfattning : Phase locked loop (PLLs) are the keystone for the electronic as well as for the communication circuits. Without any exaggeration, PLLs are found almost in every electronic and communication devices. Countless research has been performed, for the modification and enhancement of the PLLs circuit.

  4. 23. Low-power 8-bit Pipelined ADC with current mode Multiplying Digital-to-Analog Converter (MDAC)

    Master-uppsats, Institutionen för systemteknik

    Författare :Khurram Shahzad; [2009]
    Nyckelord :ADC; Pipelined ADC; MDAC; ENOB; low-power; digital error-correction;

    Sammanfattning : In order to convert the analog information in the digital domain, pipelined analog-to-digital converter (ADC) offers an optimum balance of resolution, speed, power consumption, size and design effort. In this thesis work we design and optimize a 8-bit pipelined ADC for low-power. The ADC has stage resolution of 1. LÄS MER

  5. 24. On the Design of an Analog Front-End for an X-Ray Detector

    Master-uppsats, Institutionen för systemteknik

    Författare :Farooq ul Amin; [2009]
    Nyckelord :Readout Electronics; CMOS Analog Front-End; Low Power; Low Noise; Charge Sensitive Amplifier CSA ; Gm-C Filter; Pole-Zero cancellation circuit;

    Sammanfattning : Rapid development in CMOS technology has resulted in its suitability for the implementation of readout front-end systems in terms of high integration density, and low power consumption yet at the same time posing many challenges for analog circuits design like readout front-end. One of the significant challenges is the low noise design for high speed front-end systems, while at the same time minimizing the power consumption as much as possible. LÄS MER

  7. 25. Development of water leakage detectors

    Magister-uppsats, Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Författare :Anders Pettersson; [2008]
    Nyckelord :;

    Sammanfattning : One of the highest costs in many apartments for insurance companies is due to water leakage. To prevent leakage from causing damage a detector can be placed in the sensitive areas to warn if a leakage should occur. LÄS MER
