... 1. In a typical MOSFET device there is always a trade-off between the on current and the output conductance and the channel doping. Low channel doping is required to get more inversion layer electrons, but that can lead to large output conductance and punchthrough effect. To prevent the punch-throug ...

Metadyne
A metadyne is a direct current electrical machine with two pairs of brushes. It can be used as an amplifier or rotary transformer. It is similar to a third brush dynamo but has additional regulator or ""variator"" windings. It is also similar to an amplidyne except that the latter has a compensating winding which fully counteracts the effect of the flux produced by the load current. The technical description is ""a cross-field direct current machine designed to utilize armature reaction"". A metadyne can convert a constant-voltage input into a constant-current, variable-voltage output.
