Abstract

A novel superconducting device based on voltage controlled critical current suppression has been demonstrated, with the capability of being employed as a superconducting three terminal gate-assisted transistor: the EF-Tron. In this work, we explore the potential of the EF-Tron for building superconducting logic elements. We have developed a continuous Verilog-A model and performed SPICE simulations of different logical circuits, including examples of combinatorial, sequential circuits, and ring oscillator. The simulation results will provide guidance for device design, manufacturing, and experimental testing. The obtained results and developed circuits can be used as logical building blocks for an Arithmetic-Logic Unit (ALU) and further scaled to more complex digital designs
