Routability of twisted common-centroid capacitor array under signal coupling constraints
international midwest symposium on circuits and systems, pp. 1-4, 2016.
We address layout generation of on-chip matched capacitors with the high relative accuracy. Our twisted common-centroid pattern of unit capacitors consider the post-placement routability as well as reduce a systematic mismatch induced by process gradient. We apply this algorithm to the layout design of an SAR-ADC circuit. Compared with th...More
