Spin Wave Normalization Toward All Magnonic Circuits

The key enabling factor for Spin Wave (SW) technology utilization building ultra low power circuits is the ability to energy efficiently cascade SW basic computation blocks. Majority gates, which constitute a universal gate set this paradigm, operating on phase encoded data are not input output coherent in terms of amplitude, and as such, their cascading requires information representation conversion from voltage back, by no means effective. In paper, novel free scheme proposed that achieves amplitude normalization directional coupler. After introducing concept, we utilize it implementation three simple and, demonstrate its bigger scale potential, 2-bit inputs multiplier. structures validated Object Oriented Micromagnetic Framework (OOMMF) GPU-accelerated Micromagnetics (MuMax3). Furthermore, assess induced overhead approach consumes 20% 33% less when compared with transducers based conventional counterpart. Finally, introduce multiplier design compare functionally equivalent transducer 16nm CMOS designs. Our evaluation indicate provided 26% 6.25x reductions counterpart, respectively, demonstrates our proposal effective opens road towards full paradigm potential development only circuits.
