Abstract
A differential amplifier current steering circuit wherein the active circuit elements are realized as field emission devices (FEDs) which provide for an extended range of operation to include modulation/demodulation applications up to the order of one Terahertz and digital logic function applications up to the order of one hundred gigabits per second. In a particular embodiment of the FED switching circuit vertical integration of selectively interconnected FEDs is employed to provide the desired switching circuit function.
