Abstract: A cascode current mirror for use as a biasing element or as a load device for amplifier stages in which the output resistance is increased so as to produce a substantially lower change in output current as supply voltages vary. The cascode current mirror incorporates an amplifier connected to provide negative feedback on the output cascode transistors in boosting the output resistance by a factor equal to the amplifier gain.

Abstract: A gas turbine engine carburetor including an annular swirler and a new and improved fuel injector cooperating therewith is disclosed which is effective for providing low BTU gaseous fuel to a combustor. The swirler includes a plurality of circumferentially spaced swirler vanes effective for channeling air along an annular inner surface of the swirler. The fuel injector includes a hollow injector tip having an aft portion including a plurality of circumferentially spaced outlet apertures disposed in an outer surface thereof. The outer surface is aligned obliquely to a longitudinal centerline axis of the injector tip and the swirler.
