Programmable analog signal conditioning circuits can be programmed in the field to permit their use in several applications with a variety of sensors with different output signal characteristics. The digital programming of the gain and dc level shift of a conditioning circuit can affect the measurement resolution and cause a reduction in the range of the(More)
According to the Food and Drug Administration, infusion pumps are considered nowadays the most safety-critical medical device due to the nature of their operations and associated risks. The design of these devices is still an open question and several improvement initiatives are under research. However the released specifications of such systems are not yet(More)
 The combination of transducers and microprocessors facilitate the insertion of a device called smart sensor in a digital communication network and decrease the efforts of proper configuration. However, the diversity of existing protocols or the creation of independent solutions by manufacturers hinders the interoperability of these transducers, making(More)
This paper presents an analysis and system-level design of an incremental sigma-delta converter (IΣΔ ADC) in order to explore a possible solution to low power multi-channel applications. The problem of using classic ΣΔ ADCs for applications which require time multiplexed signals will be discussed. The IΣΔ ADCs are(More)
