Study on the electromagnetic susceptibility of a high precision integrated temperature sensor

An electronic system is compatible with its electromagnetic environment if it satisfies the following two criteria: it does not emit (unintentional) electromagnetic energy above a certain minimum level, and it is not susceptible to malfunction if unintentional electromagnetic energy below a certain level is incident on it. This paper presents a study on the effect that electromagnetic interferences have on a high precision temperature sensor. An experimental setup was created to generate the radiated emissions, and results were analyzed using DSP processing. The perturbation signal obtained was applied on the temperature sensor supply voltage and results were analyzed.
