  1. 1. Fast Clock Synchronization for Large-Scale MEMS Ultrasonic Transducer Arrays

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Karl-Johan Karlsson; [2022]
    Nyckelord :clock synchronization; clock deskew; MEMS transducer; Delay line; Time-to-Digital conveter;

    Sammanfattning : In many systems today sensors or transmitters need to be read or controlled simultaneously. This thesis investigates a new architecture used for deskewing clock signals between multiple separated parts of a signal transmission system. LÄS MER

  3. 2. Study of HfN as seed layer for next generation of BAW RF filters : synthesis, characterization, and investigation of piezoelectric performance

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Sammanfattning : Micro-electro-mechanical systems (MEMS) have become an essential component of a wide range ofelectronic devices over the last decades such as accelerometers, microphones, gas sensors, and filters.During this new millennium, a new radio frequency (RF) technology has been developed to satisfy thetough demands that arose due to the implementation of 5G wireless communication: bulk acoustic wave(BAW) filters.

  4. 3. Exploiting free-eld PNAH in the presence of a reecting surface

    Master-uppsats, KTH/MWL Marcus Wallenberg Laboratoriet

    Författare :Luca Manzari; [2015]
    Nyckelord :;

    Sammanfattning : In the scope of developing a framework to perform nearfield acoustic imaging in bounded environments, the behavior of free-field methods in the presence of a reflecting surface has been explored. Intensive parametrization has been operated on the variables defining the system, and the forward propagation of the pressure field has been performed both with a plane wave synhtesis and a wave field extrapolation method.
