The use of heterojunction double-barrier diodes in logic circuits is examined. Switching time limitations are estimated based on circuit considerations and device architecture. Dispersion effects involving quantum mechanical resonant tunneling time delay are also included. These theoretical considerations indicate that picosecond or subpicosecond switching times might be achievable with appropriately designed AlxGa1-xAs/GaAs devices.
