Abstract :
We study an analog-to-digital converter (ADC) that uses ternary quantizers consisting of resonant-tunneling diodes and HEMTs. This paper explains the ADC design and presents experimental results. A resonant-tunneling ternary quantizer operates at 10 GHz and a 2-bit ADC operates at 5 GHz.
