- ``pn_ratio="<float>"`` specify the ratio between *p*-type and *n*-type transistors. The ratio will be used when building circuit structures such as inverters, buffers, etc.

Specify device-level parameters for transistors
- ``name="<string>"`` specify the name of the p/n type transistor, which can be found in the manual of the technology provider.
- ``chan_length="<float>"`` specify the channel length of *p/n* type transistor.
- ``chan_length="<float>"`` specify the channel length of a *p/n* type transistor.
- ``min_width="<float>"`` specify the minimum width of *p/n* type transistor. This parameter will be used in building inverter, buffer, *etc*. as a base number for transistor sizing.
- ``min_width="<float>"`` specify the minimum width of a *p/n* type transistor. This parameter will be used in building inverter, buffer, *etc*. as a base number for transistor sizing.
- ``max_width="<float>"`` specify the maximum width of a *p/n* type transistor. This parameter will be used in building inverter, buffer, *etc*. as a base number for transistor sizing. If the required transistor width exceeds the maximum width, multiple transistors will be instanciated. Note that for FinFET technology, your ``max_width`` should be the same as your ``min_width``.
.. note:: The ``max_width`` is optional. By default, it will be set to be same as the ``min_width``.
- ``variation="<string>"`` specify the variation name defined in the ``<variation_library>``
