The Bell Northern Research arm of Bell Canada has developed a Gallium Arsenide multiplier chip capable of multiplying two four-digit binary numbers in one nanosecond for digital signal processing applications. It will be integrated into Northern Telecom’s future switching and fibre optic transmission systems. Made on a three-inch wafer of Gallium Arsenide, the product is fabricated to one micron design rules. Bell Northern says it will put together a Gallium Arsenide circuit library.
