  The oscillator-based Ising machine (OIM) is a network of coupled CMOS
oscillators that solves combinatorial optimization problems. In this paper, the
distribution of the injection-locking oscillations throughout the circuit is
proposed to accelerate the phase-locking of the OIM. The implications of the
proposed technique theoretically investigated and verified by extensive
simulations in EDA tools with a $130~nm$ PTM model. By distributing the
injective signal of the super-harmonic oscillator, the speed is increased by
$219.8\%$ with negligible increase in the power dissipation and phase-locking
error of the device due to the distributed technique.
