Abstract
Resonant tunneling diodes (RTDs) are receiving much attention because of their high-speed switching capability and functional versatility. Due to the negative differential resistance exhibited by RTDs, great functionality with a single gate can be achieved. In this paper, novel universal threshold logic gates (UTLG) based on RTD with simple structure and fixed parameter are proposed. The three-variable UTLG implement all the threshold functions of three variables by reconfiguring the input bits. The proposed circuit can also be applied to the design of arbitrary logic function in a multilevel threshold network. Finally, the operation of UTLG is verified by HSPICE simulation using extensively validated models.
