Abstract-We present a capacitive digital-to-analog converter (DAC) architecture combining properties of the binary-weighted and serial charge-redistribution DACs to yield high integration density and high accuracy. The architecture provides the flexibility to trade area with conversion speed based on a set of area-speed-linearity constraints. We validate the architecture using a 10-bit two-step DAC example, simulated in a standard 0.35 m CMOS technology. The 10-bit DAC occupies 32 times less area than the conventional 10-bit binary-weighted DAC, has low INL, good matching, and high tolerance to parasitic capacitance.
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.
