Abstract :
The use of novel resonant tunneling devices in fuzzy logic hardware has been demonstrated previously (H. Tang, H.C. Lin, 1994). The results have shown great improvement in speed and reduced circuit complexity. However, one major problem associated with these resonant tunneling diodes (RTDs) is the hysteretic effect which in some applications may deteriorate circuit performance considerably. The paper suggests a method to eliminate the hysteresis effect by the use of input sampling. The sampled input will have unique value on the membership function generated from the RTD´s intrinsic I-V characteristics
