  1. 1. Implementation of PID control using Arduino microcontrollers for glucose measurements and micro incubator applications

    Kandidat-uppsats, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Hugo Andersson; Viktor Mattsson; Aleksandar Senek; [2015]
    Nyckelord :;

    Sammanfattning : The task is to build a low-cost thermostat and design necessary elements to perform a study on water mixed glucose-impedance at different temperatures and cell growth in a temperature-controlled incubator housing a magnetic field of up to 3 mT. The incubator was designed in solidworks and made to fit petri dishes of two relevant sizes and necessary wiring. LÄS MER

  3. 2. DC to DC converter for smart dust

    Master-uppsats, Institutionen för systemteknik; Tekniska högskolan

    Författare :Kashif Nisar; [2012]
    Nyckelord :Comparator; DC to DC converter; PWM; Op-amp; Voltage regulator;

    Sammanfattning : This work describes the implementation of DC to DC converter for Smart Dust in 65 nm CMOS technology. The purpose of a DC to DC converter is to convert a battery voltage of 1 Vto a lower voltage of 0.5 V used by the processor. LÄS MER

  4. 3. Oscillators with Constant Frequency over PVT

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Guodong Guo; [2012]
    Nyckelord :;

    Sammanfattning : This thesis is offered by Texas Instruments, Germany, aimed at designing an on-chip oscillator with constant frequency over process, voltage and temperature variation. RC relaxation oscillator is chosen to be the solution due to its small area and proper frequency accuracy. LÄS MER

  5. 4. Design of a Low Power Cyclic/Algorithmic Analog-to-Digital Converter in a 130nm CMOS Process

    Master-uppsats, Elektroniksystem; Tekniska högskolan

    Författare :Ajith kumar Puppala; [2012]
    Nyckelord :Redundant Signed Digit; Correlated level Shifting; Low power; High Speed; Folded cascode;

    Sammanfattning : Analog-to-digital converters are inevitable in the modern communication systems and there is always a need for the design of low-power converters. There are different A/D architectures to achieve medium resolution at medium speeds and among all those Cyclic/Algorithmic structure stands out due to its low hardware complexity and less die area costs.

  7. 5. Investigation of silicon PIN-detector for laser pulse detection

    Magister-uppsats, Institutionen för teknik och naturvetenskap

    Författare :Sam Chau; [2004]
    Nyckelord :Laserdiode; photodiode; silicon PIN-detector; operational amplifier; responsivity; differential efficiency; bandwidth; feedback network;

    Sammanfattning : This report has been written at SAAB Bofors Dynamics (SBD) AB in Gothenburg at the department of optronic systems. In military observation operations, a target to hit is chosen by illumination of a laser designator. From the targetpoint laser radiation is reflected on a detector that helps identify the target.
