ROA-Based Subharmonic Injection Locking for Oscillator-Based Ising Machines

Baris Taskin, Nicholas Sica

Rotary oscillator array bricks enable stable subharmonic injection locking signals that preserve solution accuracy in oscillator-based Ising machines under PVT variations.

Claims

C1strongest claim

Under PVT variations, distributed ring oscillator-based SHILs fail to perform injection locking while the proposed ROA brick-based SHIL preserves 93% to 97% accuracy (the same accuracy of an ideal SHIL signal) in the OIM solutions of a sample 324-node max-cut problem.

C2weakest assumption

The simulations of the ROA brick topology accurately capture the phase stability and driving strength needed for real on-chip integration without introducing unmodeled coupling or layout parasitics that would degrade the SHIL process (abstract and implied in the PVT variation claims).

C3one line summary

ROA-based SHIL delivers a stable 2.31 GHz signal under PVT variations and preserves 93-97% solution accuracy on a 324-node max-cut problem in OIMs where ring-oscillator SHIL fails.
