Dear all,
Who can tell me how to choose the mismatch value of the res to design the 7bit DAC with 128 res in series?
I know that a larger size makes a smaller mismatch, but I don't kown what mismatch value can meet my spec.
Could you show me some paper about this? Thanks!
The foundry always serve some paper for the PCM or spice model of the resistor, which contains the mismatch VS the W L of the resistor. you can look for it.
