请问不同工艺角下如何调整让电路性能一致

那只有重新设计参数了，在设计参数时，要尽量留有余量

还有可以用trim的方法

电路设计裕量小，重新调

1. ratio design
2. redesign with different architecture like folded-cascode...etc.
3. usually a MOS with its length near the minimum, it may demonstrate a larger Vt variation under different corners. You may review this point by checking the second-order approximation of MOS current.
