Résumé: Sensor systems have applications in environmental, medical and industrial monitoring and should communicate with remote centers of expertise for diagnosis and follow-up action. Some of the most important challenges in (especially) health-care technologies have been identified to be development of noninvasive systems and miniaturization. In developing core technologies, progress is required in pushing the limits of miniaturization, minimizing the costs and power consumption of microsystems components, towards so-called “Lab-in-a-pill”. The implementation of such miniaturized systems has become feasible by the advent of system-on-chip technology, which enables us to integrate most of the components of a system on to a single chip. IDEAS, which is an acronym for ‘Integrated Diagnostics for Environmental and Analytical Systems’ is a thumb-nail sized sensor that can be swallowed. It is capable of measuring pH, conductivity, dissolved oxygen concentration, and temperature in the gastrointestinal tract. One of the most important tasks in such a system is to convey information reliably on a multiple-access-based environment. Communication systems targeting such miniaturized sensor microsystem networks are characterized by their restricted power and area constraints. When considering the design of telecommunication system for such a network, the receiver is the key performance critical block. In this talk, the application environment, the choice of the communication protocol, and the implementation of the transmitter and receiver circuitry will be presented. In particular, research work carried out on studying the impact of input data characteristics and internal data path complexity on area and power performance of the receiver will discussed. It has been demonstrated that up to 59% and 11% savings in area and power, respectively, could be achieved by optimizing input data size and internal register width particular applications while maintaining signal quality.
