hi everybody
I am intending to analysis the circuit in ADS for mismatch betwin cmos transistors and i use the tech lib : UMC180. i mean that there are some tolarances for W, L and threshold voltage of the cmos transistors. can any body help me to do it in ADS?
thanks in advance.
 

In addition to random mismatch between transistors, there may be a systematic mismatch caused by the layout - like difference in power/ground nets resistance and IR voltage drop for the two (or for many) transistors, difference in resistance and/or delay on other nets connected to them, difference in device instance parameters caused by layout (such as well proximity effect, stress effect, etc.) - these also need to be analyzed and verified (especially in advanced nodes with high parasitics).
