1)why we use this type of pattern ( SQUARE SHAPE) for BJT matching , but not for CMOS? what is the difference between BJT and MOS matching?
2)can we use 24:1 for BJT. which is better 8:1 or 24:1? why?
3)If there are two devices 2:3, 2:4 or 3:4. how can we match them ( i mean in which pattern, is one dimension or two dimension). can we use dummies to fill places?
example: can we use for 6:1 (M2:M1) like below
M2 M2 M2
D M1 D
M2 M2 M2
Here D means dummies. can we fill the places to get Square structure with dummies?
please clarify doubts friends
