Abstract:Abstract-Voltage scaling is a promising approach to reduce the power consumption in signal processing circuits. However aggressive voltage scaling can introduce errors in the output signal, thus degrading the algorithmic performance of the circuit. We consider the specific case of the finite impulse response (FIR) filter, and identify two different sources of errors occurring due to voltage scaling: (a) errors introduced because of increased delay along the logic path and (b) errors caused by failures in the m… 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.
