about parasitic capacitor between pads

[memsgg]

Does anyone know the value of parasitic capacitor between two pads on chip? several pf?

And if we connect two naked chips by wire bonding their pads, how many pf parasitic capacitor is induced?

Many thanks

i think it is in the range of 4-5pf.

 

[memsgg]

really?

I think it is about 1pf

and it depends on the distance between wires, if we leave enough distance, say 1cm, it should be very small, say <1pf, is it right?

i am not sure about it.
But at least 2pf should be there.
