Hi all ,
Resently I have simulated the SNDR of a 12b Current sterring DAC ,but it is only 54dB, thus the enob is 9bit . Simulation by Cadence without mc model.
So, I'm very confused why the DAC's SNDR was so bad ?
Can anyone give me some help?
By the way, How to tradoff the transistors' size of current source for the Statics and Dynamic performance ?
