pipelineADC中MDAC尾电流的确定

billlin · 发表于 2016-4-27 17:03:49

SR time =1.25nsec
CV=Ixt
300fF*1V=I*1.25nsec
I=240uA
Example 3mA ???
Can not understand ???

Example tail curent is dominated by small settling time
and need very Big OP Unity-gain frequency
To 1GHz unity-gain frequency is normal.
the 3mA is not calculated by SR Limitation constraint
