Abstract

This paper demonstrates the design of nanomagnetic logic (NML) gates with multiple weighted inputs, which are magnetic equivalents of threshold logic gates (TLGs). We use micromagnetic simulations to show that NML TLGs can be constructed with minimum overhead compared to standard NML gates, and they significantly reduce device footprint and interconnection complexity of magnetic logic circuits. As an example, we design a full adder circuit using said TLGs and compare its performance to majority-gate-based NML.
