I'm looking for the equation which relates Vgs1, Vth1, Vgs2, and Vth2 to Id.
For a single gate MOSFET, this is:
\[{I}_{D}={I}_{DSS} \cdot \left[ \left( {V}_{GS} - {V}_{TH}\right) \cdot {V}_{DS} - \frac{ {{V}_{DS}}^{2} }{2}\right]\]
or the approximation
\[{I}_{D}={I}_{DSS} \cdot \left( {V}_{GS} - {V}_{TH} \right) \cdot {V}_{DS}\]
where
\[{I}_{DSS}={k}_{n}\left(\frac{W}{L}\right)\]
I haven't found much about how to apply this to dual gate MOSFETs, however.
