CADENCE capacitor corners max min typ meaning

Ricardo Alves

Hi all,

Please anyone can tell me what is the meaning of max, min, and typ for capacitors corners.

I understand that the parameters ss or ff corresponds to the mobility ( slow slow, fast fast) of the electrons in MOS devices. But i don´t understand what are the changes in the model of the capacitors when we apply the corners whith these variations for capacitors (max, min and typ).

Thanks in advance.

 Best regards. 

  • The manufacturing processes will cause some variation in the thickness of the dielectric (eg the gate oxide for a MOS cap, the oxide between metal layers for a finger cap, etc) and also metal thickness and track widths - this will vary the capacitor values and hence it makes sense to have corners representing those extremes. 

    Regards,

    Andrew
