An analog-to-quaternary quantizer using resonant-tunneling (RT) devices is applied to an ultrahigh-speed analog-to-digital (A/D) converter. First, transient analysis results for the quaternary quantizer, which consists of six RT diodes and one HEMT, are presented. A 4-bit A/D converter employing thi...
