segmented dac

基本解釋

The dissertation designs a 12-bit"4-4-4"segmented current steering DAC.
本文設計的數模轉換器是一個“4-4-4”分段的12位電流舵型DAC。
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.
通過對DAC結構的比較，決定采用分段式電流舵結構，其中高5位采用溫度計碼，低3位采用二進制譯碼。
At the present time, digital to analog converter use the current steer configuration mostly and the segmented configuration thereinto is fit for the design of high-speed, high-precision DAC.
目前，數模轉換器大多采用電流舵型結構，而其中的分段式結構又比較適合于設計高速高精度的數模轉換器。
