Jl. Huber et al., AN RTD TRANSISTOR SWITCHING BLOCK AND ITS POSSIBLE APPLICATION IN BINARY AND TERNARY ADDERS/, I.E.E.E. transactions on electron devices, 44(12), 1997, pp. 2149-2153
We propose and demonstrate both a binary and ternary adder circuit bas
ed on a resonant tunneling diode (RTD) and a bipolar transistor, The b
asic switching cell consists of an RTD in series with the base of a bi
polar transistor, The RTD is used to set a threshold voltage for the s
witching of the transistor.
