Analog-to-Digital Converters using not Multi-Level but Multi-Bit Feedback Paths
Proc. 2017 IEEE 47th International Symposium on Multiple-Valued Logic   7-12   May 2017   [Refereed]
Conventional analog-to-digital converters (ADCs) with medium or high bit-resolution have a feedback path that connects a tentative digital output with the analog input to obtain a final digital output. Digital-to-analog converters (DACs) are used ...
