Overview (resum en anglès):
The dissertation main purpose is to determine the noise level contribution for a \gls{lisa} electronic prototype. The thesis covers insights over sub-millihertz frequencies, from theoretical and experimental sensor noise performance to temperature measurements. The project aims to contribute to the \gls{ieec} research
focused on developing high stable equipment for the \gls{esa}'s first space based gravitational wave observatory called \gls{lisa}. This pioneering mission will enhance the knowledge about numerous intriguing concepts regarding the beginning and evolution of the universe. For instance, black holes and galaxy formation along with general relativity theory. Notwithstanding, the temperature fluctuations coming from the spacecraft electronics could perturb the \gls{gw} measurements, hence this is where the dissertation takes over. Firstly, a brief introduction regarding the \gls{gw} and the need for their detection is provided. Further to this, the dissertation presents the \gls{lisa} temperature requirements and analyses. Afterwards, the dissertation analyses, theoretically and experimentally, the temperature coefficient for a \gls{lisa} electronics prototype, with the subsequent study of the noise projection analysis. The thesis has been built on the considerable effort previously made by the \gls{ieec} team.
