Abstract
Normally-off GaAs m.e.s.f.e.t. logic circuits fabricated by electron beam lithography have exhibited excellent high speed switching characteristics. The highest switching speed evaluated from a 15-stage ring oscillator is 30 ps per gate with a power dissipation of 1.9 mW. Binary frequency dividers have been fabricated with D-type flip-flops operating up to 3 GHz. A divide-by-eight counter has also operated at 2.5 GHz.
