Low power signal processing systems are required for distributed network microsensor technology.Network microsensors now provide a new monitoring and control capability for civil and military applications in transportation, manufacturing, biomedical technology, environmental management, and safety and security systems. Signal processing methods for event detection have been developed with low power, parallel architectures that optimize performance for unique sensor system requirements. Implementation of parallel datapatbs with shared arithmetic elements enables high throughput at low clock rate. This method has been used to implement a microsensor spectrum analyzer for a 200 sample/s measurement system. This 0.8p CMOS device operates with a 1M drain current at a 3V supply bias.
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.
