摘要
We report master-slave D-type flip-flop (D-FF) circuit implemented with AlGaAs/GaAs HBT's. The fabricated HBT's had an f(T) of 107 GHz and an f(max) of 110 GHz, To maximize the speed, the logic swing and transistor size in the IC were optimized. in the D-FF, to facilitate the high-speed testing, a selector circuit was integrated on the same chip, As a result, the operation of this IC was confirmed up to 40 GHz, which is the highest speed in D-FF.
