calculate gmt and cte
Hi,
You can use not only strong inverse MOS capacitor.
May be better to use capacitor w/o inverse layer, for example, NMOS in NWell (N+ drain and source in NWell). It's so called Accumulation MOS (AMOS) capacitor.
It's easy to simulate this capacitor in SPICE - use PMOS model, node connection - Gate and Bulk.
More detail you can see in
