| 1. An integrated circuit comprising:
a) a substrate;
b) a thyristor device formed on said substrate, said thyristor device having at least one modulation doped quantum well structure
that defines a channel region, an anode terminal electrode, a cathode terminal electrode, and at least one control terminal
electrode that is operably coupled to said modulation doped quantum well structure; and
c) at least one current source means, operably coupled to said control terminal electrode, for drawing charge from said channel
region.
