Using multi-threshold threshold gates in rtd-based logic design. A case study
(Laboratoire TIMA, 2007)
The basic building blocks for Resonant Tunnelling Diode (RTD) logic circuits are Threshold Gates (TGs) instead of the conventional Boolean gates (AND, OR, NAND, NOR) due to the fact that, when designing with RTDs, ...
