Abstract:There is a trade-off between resolution and acquisition range of voltage while performance of feedback control depends on the resolution. Many signals in motion control change quickly with various range and hence both of saturation avoidance and high-resolution data-acquisition are one of the challenges. This research proposes a multi-amplification technique which provides a wide-range and high-resolution A/D conversion. A high-frequency-operated circuit and a fast processor on an FPGA are developed and then a… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
