def DC_drift_region(self, *args, **kw):

Builds a circuit with analysis.mosfet_model.MOSFET_Model.drift_region and does a DC analysis on it with the supplied args.

Returns a Deferred that fires with the Vectors_Ngspice object populated with V(10), V(16), and V(19). Also internal node voltage V(18) between the accumulation and JFET region modeling inside the drift region.:
