Cyclic digital to analog converter in pipeline structure

摘要

A cyclic digital to analog converter (CDAC) in a pipeline structure includes a first CDAC block and a second CDAC block. The first CDAC block receives a first digital signal and converts the first digital signal to a first analog value. The first CDAC block includes a charging capacitor for charging according to the first digital signal and a first storing capacitor for storing the first analog value. The second CDAC block receives a second digital signal and converts the second digital signal to a second analog value. The second CDAC block includes the charging capacitor for charging according to the second digital signal and a second storing capacitor for storing the second analog value. The first CDAC block and the second CDAC block share the charging capacitor.
