Capacitor and guard bar

[pat_fr]

Hi all,

Does a capacitor need a guard bar or not ? and why ?

Thanks

At a glance it need a guard band if it's a large area.

There are several ways to build capacitor according to the material used.

Usually parasitic capacitance will be build within the transistor it self, but the value is small...

we need a guard bar coz we are affraid that it will cause signal delay and also higher power density.
