"In general, in the chip spare space we add moscap(gate connect to one power rail, and source-drain connect to the other power rail) for decoupling as moscap has most unit capacitor?'
why do we use unit capacitor ?
for example, why not use one big mos cap? why use large capacitor by parallel unit cell?
