Abstract :
We report on the successful demonstration of a functionally complete set of logic gates based on resonant interband tunneling diodes (RITDs) with a maximum operating frequency in excess of 12 GHz. At this high frequency of operation, the power dissipation is remarkably low-on the order of 0.5 mW per gate. The circuits for all gates, AND, OR, XOR, and INV, shared the same layout geometry, consisting of two Schottky diodes and three RITDs. Logical functionality was determined solely by varying the relative areas of the devices
