A High Speed 6x6 Bit Parallel Multiplier Using Self-Aligned Refractory Gate GaAs/AlGaAs Heterostructure FETs

A 6x6 bit parallel multiplier was designed in Self-Aligned GaAs/AlGaAs Heterostructure FETs for demonstrating design and fabrication capabilities of an LSI GaAs pilot production line. Initial results shows that the chips are fully functional from 1.7 to 2.3 volt supply and multiplication time measured from wafers is 7.8 ns, which is equivalent to a delay fo 244 ps/gate at 0.94 mW/gate.
