EMI susceptibility issue in analog front-end for sensor applications

The susceptibility to electromagnetic interferences of the analog circuits used in the sensor readout front-end is discussed. analog circuits still play indeed a crucial role in sensor signal acquisition due to the analog nature of sensory signals. the effect of electromagnetic interferences has been simulated and measured in many commercial and integrated analog circuits; the main cause of the electromagnetic susceptibility is investigated and the guidelines to design high emi immunity circuits are provided. © 2016 anna richelli.
