Environmental electromagnetic pollution has drastically increased over the last decades. The omnipresence of communication systems, various electronic appliances and the use of ever increasing frequencies, all contribute to a noisy electromagnetic environment which acts detrimentally on sensitive electronic equipment. Integrated circuits must be able to operate satisfactorily while cohabiting harmoniously in the same appliance, and not generate intolerable levels of electromagnetic emission, while maintaining a sound immunity to potential electromagnetic disturbances: analog integrated circuits are in particular more easily disturbed than their digital counterparts, since they don't have the benefit of dealing with predefined levels ensuring an innate immunity to disturbances. In addition, as different electronic systems are compactly integrated in the same apparatus, the parasitic electromagnetic coupling between these circuits sharing the same signal, power and ground lines, is a critical design parameter that can no longer be safely excluded from a product design flow: as an example, Bluetooth, GSM and WiFi services have to coexist and operate in harmony within the crammed confinement of a modern mobile phone. The objective of the research domain presented in EMC of Analog Integrated Circuits is to improve the electromagnetic immunity of considered analog integrated circuits, so that they start to fail at relevantly higher conduction levels than before.

The measurement of signals from human body is achieved usually through the use of electrodes in direct contact with skin. Typically, these measurements are performed using Ag/AgCl electrodes with conductive gels or dry contact electrodes in direct contact with skin. In recent years, non-contact electrodes have been considered as an alternative option offer several benefits such as stability over time in long-term monitoring applications, the ability to make the signal monitoring more comfortable for the patient and it does not require the presence of qualified medical staff. &#13;The aim of this thesis is to design and implement a contactless sensory system for the detection of ECG signals. The approach is based on a coupling with human body performed by electrodes integrated in a front-end circuit, detects changes of electric charge that are related to cardio muscle activity. The signal from the human body generally characterized by low intensity and narrow bandwidth, and also the electrodes do not perfectly transmit the signal and distort the signals slightly. Therefore, due to the presence of other undesired signals suitable amplifications and analogue filters are required in order to obtaining a clear signal.
