Operating Voltages where SPICE models are valid
- \|V\ :sub:`c0` – V\ :sub:`c1`\ \| = 0 to 5.0V
Details
~~~~~~~
The MiM capacitor is constructed using a thin dielectric over metal, followed by a thin conductor layer on top of the dielectric. There are two possible constructions:
- CAPM over Metal-3
- CAP2M over Metal-4
The constructions are identical, and the capacitors may be stacked to maximize total capacitance.
Electrical specs are listed below:

The symbol for the MiM capacitor is shown below. Note that the cap model is a sub-circuit which accounts for the parasitic contact resistance and the parasitic capacitance from the bottom plate to substrate.
