Abstract:Wireless sensor network applications typically include various sensors (temperature, humidity, gas, etc.) and each sensor has different requirements of speed, noise, offset, and power consumption. In order to optimize the performance and allow long-time operation, reconfigurability is mostly desirable in the readout circuitry. In this paper, a reconfigurable time-domain comparator (RTDC) with low noise and low offset is proposed, mainly for reconfigurable SAR ADCs in wireless sensor nodes. With a supply volta… 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.
