  1. 1. Microwave Transistor Noise Model Extraction Methods and a Non-Contacting Scattering Parameter Measurement Method

    Författare :Jörgen Stenarson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extraction; S-parameter; noise parameter; vector network analyzer; electro-magnetic probe; microwave; non-contacting testing; transistor noise model; VNA; EM-probe; non-invasive testing;

    Sammanfattning : This thesis has two parts. The first part discuss noise model extraction methods for FETs. The second part describe theory and implementation of a non-contacting S-parameter measurement method. Noise is an important aspect for a circuit designer, because noise generated in the circuit is a sensitivity limiting factor. LÄS MER

  3. 2. TV holography and shearography in experimental mechanics

    Sammanfattning : TV holography is an optical non-contacting whole field technique to measure deformation. Names as ESPI or Electronic speckle pattern interferometry, Electro-optic holography and Electronic holography are commonly used for this real-time video based interferometric technique. Shearography has become an important tool in non destructive testing. LÄS MER
