dc.title : Study and measurements of nominal linear components
dc.creator : HERVELLA, David Lorenzo
dc.subject :
dc.description.abstract : Abstract Contrary to popular belief passive components such as capacitors, inductors and even interconnects can cause distortion of signals. This is even more becoming true with the minaturisation of components. Generally this distortion is dependent on choice of materials and geometry of the components and their contacts. In many cases the distortion is bias dependent. If it all, only minimal information is available to the designer. Manufacturers generally don't specify distortion figures and literarature is many times subjective and misleading, especially in the audio world. The aim of this work is to set up an easy to use and performent measurement system and to analyse and categorize components and causes. And ultra low distortion signal generator (1KHz) is built with selected components. This 1 KHz signal is send through the DUT and then attenuated with a Tee notch filter (-65dB). The spectrum then is further amplified and FFT analysed on PC for distortion.DC biasing of the DUT is also possible. Distortion can instantly be analysed and interpreated from the obtained measurements. With this measurement set up, the designer has an easy to use tool to measure and compare components of his design. Values of distortion have been found that are important in critical design such as instrumental amplifiers, low phase noise circuits, confirming previous findings.Harmonic distortion sometimes can be lowered by tens of dB's by using a proper selected capacitor. Several components , built in different technologies will be measured and selection criteria will be set up for these nominal linear components.
