Abstract:The paper discusses the design of a very highspeed 8-b analog-to-digital converter (ADC) in 0.18-µm CMOS. A conversion rate as high as 2GS/s with a relatively low power consumption was achieved by means of a couple of interleaved subranging/flash ADCs with a single Track-andHold at the input. Special design solutions were adopted for implementing subranging operation at such a high frequency. Finally, a lower power consumption self-calibrating technique effective for reducing non linearity errors below 1 LSB w… 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.
