How to distinguish the positive and negative plates of a MIM capacitor in layout as well as in schematic ? using a lengthy or small metal 6 layer which is preferred for connecting? I found that it is good to put metal layer contacts outside the capacitor. Is this right? I am here adding one picture of the layout view of one MIM capacitor.

we can identify the top & bottom plate by checking the layers. For eg: if a mim is comprising of Poly to M3 metal layers, Poly will be the bottom & M3 will be the top. For connection purpose you need to follow the MIM layout rules in the Design rule document.:grin:
