Abstract
We propose an input interface circuit that can provide input signals for the emerging all spin logic (ASL) devices. It consists of metal wires that are used for the transmission of electrical signals and magnetic tunnel junction that are used to transform electrical signals into input signals of ASL devices. The operation of input interface is validated by using a coupled spin-transport/magneto-dynamics model. A salient advantage of the proposed input interface is its ability to shorten the length of spin channel for spin transmission and avoid the complex fan-out structure when multiple identical input signals are needed. This input interface is especially useful for the design of large scale ASL circuits, in which many identical units are needed.
