Hi all,
Most of the material discussing antenna rule says that
metal antenna ratio (AR) is not cumulative (e.g. just count M2 alone, not M2 and M1 together).
But why?
Is this because the gate leakage discharges the metal which is already fabricated?
Maybe for more advanced technology, cumulative antenna ratio (CAR) is used for precise checking.
Any comment is much appreciated.
Thank you very much
