Multiple-inputresonant-tunneling (RT) logic gates have been proposed for flash analog-to-digital converter applications. An error-mode operation has been found in conventional RT gates called MOBILE when the number of input increases. By introducing an RTD/HEMT series connection to suppress the error operation, we can successfully design 4-, 8-, and 16-input RT gates, which are essential to obtain compact flash ADCs.
