Description
~~~~~~~~~~~

The PMOS model is a simple model of a p-channel metal-oxide
semiconductor FET. It differs slightly from the device used in the
SPICE simulator. For more details please care for H. Spiro.

The model does not consider capacitances. A small fixed drain-source
resistance is included (to avoid numerical difficulties).

Some typical parameter sets are:
