所述DAC进一步包括多个宏单元，每个宏单元由所述第一温度计码的一个位所控制。
The DAC further includes a plurality of macro cells with each controlled by one bit of the first thermometer code.
通过对DAC结构的比较，决定采用分段式电流舵结构，其中高5位采用温度计码，低3位采用二进制译码。
After compared some structures of DAC, the segmented architecture of current-steering DAC is adopted. The 5 MSBS are thermometer code weighed and the 3 LSBS are binary-weighted.
