Yes. We right now are not remotely in the frequency range, where such cells
would make sense.

Mohamed from eFabless offered us help, as soon as we've got the process
eFabless has some pretty experienced analog designers.
I suggest we work together with them, as soon as Victor and I have
reproducible results which warrant a measurement for simulation models
and the data sheet.
We're not quiet there though.
