Abstract Ising machines based on analog systems have the potential to accelerate the solution of ubiquitous combinatorial optimization problems. Although some artificial spins to support large-scale Ising machines have been reported, e.g., supercondu

In optoelectronic oscillators used to produce chirps for radar or communications, low phase noise usually comes at a cost of slow tuning due to mode-building time. The authors use Fourier-domain mode locking to break this limitation and enable fast-t

In order to obtain microwave signals with low spurs and low phase noise, we studied the residual phase noise of the frequency-conversion filtering oscillator and methods to improve its phase noise performance. We first analyze the influence of the di
