Ultrahigh-speed resonant tunneling circuits

By using InP-based RTD/HEMT integration technology, we fabricated ultrahigh-speed resonant-tunneling circuits, i.e., ternary and quaternary quantizers. The quantizing operation at room temperature was confirmed at a clock frequency of 10 GHz for input frequencies as high as 4.7 GHz. SPICE simulation proved that a 4-bit flash-type analog-to-digital converter which consists of the quaternary quantizers, can operate at a sampling frequency of 10 GHz.
