Title:
ISING MACHINE BASED ON COUPLED BISTABLE NODES FOR SOLVING COMBINATORIAL PROBLEMS
Document Type and Number:
WIPO Patent Application WO/2021/212145
Kind Code:
A3
Abstract:
An Ising machine having a network of resistively coupled circuit nodes where at least one node comprises a capacitor whose voltage between its terminals represents a state variable of the node and the voltage is resistively coupled to at least one other node in the network and a two-terminal active electronics element connected in parallel with the capacitor supplying energy to the node, and the element having an odd-symmetric current-voltage characteristic exhibiting a negative current gradient for voltages across its terminals that are below a predetermined threshold value in magnitude, and a positive gradient otherwise and zero current for three voltage instances: zero volts, + V1 volts, and -V1 volts, where V1 is a constant greater than the predetermined threshold.
