Abstract:Due to the extremely low amplitude of the input signals, the design of electro-neurgo-graph (ENG) amplifiers normally involves special care for flicker and thermal noise reduction. The task becomes really challenging in the case of implantable devices, because power consumption is restricted to few tens µW. In this paper, two different circuit techniques aimed to reduce flicker and thermal noise, in ultra-low noise amplifiers for implantable electronics are demonstrated. In both cases circuit design and measur… 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.
