A 720‐channel LCD source driver with a 12‐bit segmented R‐C DAC has been designed and fabricated by a 16V CMOS process. The proposed DAC consists of a conventional resistor string and a sample‐and‐hold buffer. DNL less than 0.3LSB and output voltage deviations less than 3mV were measured. Die area is 24.9mm2.
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.
