Abstract: The first gallium arsenide integrated circuit reported in 1974 contained a total of 5 depletion mode MESFETs which had a minimum 1 . 0~ gate length. The logicegates in this circuit had a minimum propagation delay of 75ps and consumed 9OmW of power, resulting in a 6.75pJ speed-power product. Chip size was 0.15 X 0.15mm. Circuit projections indicated that 2-3GHz clock rates would be feasible with logic circuits or binary dividers realized with such gates. I n 1977, a 0.4 X 0.44mm2 gate chip produced 4GHz toggle…
