—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)
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 characterized(More)
