Multi-valued decoder based on resonant tunneling diodes in current tapping mode

A multiple valued decoder based on RTDs is proposed and the functionality is verified via both simulation and experiment. The proposed circuit is simulated and tested with several single peaked RTD sections connected in series (stacked RTDs). The design uses current tapping techniques to switch on only one RTD section exclusively in order to create a single literal function. The number of RTD sections connected in series therefore determines the radix of signals used in the decoder.
