MA Long, WANG Liang-chen, YANG Fu-hua. Design of RTD-Based High Speed Multiple Value Quantizer[J]. Acta Electronica Sinica, 2005, 33(11): 2006-2008.DOI:
RTD SPICE model is built and fit to the actual RTD device fabricated on GaAs substrate.The principle of the four value quantizer circuit is explained and the simulation work is done through the extraction of device parameters.The key parameters of the circuit are established.The calculated threshold voltages of the circuit are conformed to the simulation results.Finally the maximum working frequency of the circuit is analyzed.
