一种基于CeRAM单元的数模变换器
摘要：
本发明设计了属于半导体集成电路设计和制造技术领域的一种基于CeRAM单元的数模变换器，其组成包括一组CeRAM单元和一个镜像电流源；所有CeRAM单元的WL端连接在一起，作为共同的WL端；所有CeRAM单元的DL端连接在一起，作为共同的DL端；每个CeRAM单元的BL端相互独立；DL端连接到镜像电流源的Iin端。相比于传统的数模变换器，本发明结构简单，转换速度快，在转换信号位数较多时此种优势更加明显。同时本发明应用了新型的TMO材料和CeRAM单元，在国内外均属于新颖且空白的领域，有利于占据前沿技术中的领先地位。
摘要（英）：

The invention relates to a digit-analog converter based on CeRAM unit, belonging to semiconductor integrated circuit design and production technology field. The digit-analog converter comprises a setof CeRAM unit and a mirror current source. WL terminal of all CeRAM units connects together to form a common WL terminal; DL terminal of all CeRAM unit connects together to form a common DL terminal;BL terminal of each CeRAM units is independent; DL terminal connects with Iin terminal of mirror current source. Compared with traditional digit-analog converter, the invention has simple structure, quick conversion speed. The merit is superior especially for relatively more conversion signal digit. The invention employs novel TMO material and CeRAM unit which fills the blank of home and abroad and takes advantage of occupying advanced technology field.
