Hello, How can I get the mismatch data? Cheers

Spectre also supports dc mismatch analysis, don't think it requires a special license. DC mismatch analysis is equivalent to corner analysis for mismatch. It mismatches the differential pairs by a fixed amount and calculates the sensitivity of the output to the mismatch. The ADE --> Results --> Print --> mismatch summary(?), identifies the diff pairs in order of their effect on the output. It also reports the contributions of different factors to the mismatch, for example, Vt, mobility variations, ... You can also save the operating point for use with small signal analysis, the dc operating point includes mismatch, so you evaluate the effect of mismatch on common-mode rejection, power supply rejection, etc. The big limitations are: 1) You need models with mismatch parameters 2) Transient analysis is not supported.
