ation of parameters is used in their solution. Our work not only establishes a new oscillator design aligned to the needs of the oscillator Ising machine but also advances the efforts to creating application specific analog computing platforms. A particular family of electronic oscillators uses an amplifier with a feedback path. An oscillator is a device that produces oscillations (back-and-forth) changes - usually an electronic circuit that produces AC - from a steady (DC) source of.
For example, a quartz watch uses a quartz oscillator to keep track of what time it is.
Using this oscillator design, we show experimentally, that a system of capacitively coupled EAOs exhibits the desired bipartition in the oscillator phases without the need for any external second harmonic injection, and subsequently, demonstrate its application in solving the computationally hard Maximum Cut (MaxCut) problem. Oscillators are important in many different types of electronic equipment. Unlike conventional relaxation oscillators that typically decay with a single time constant, the feedback in the EAO is engineered to generate two decay time constants which effectively helps generate the second harmonic signal internally. In this work, we experimentally demonstrate a new electronic autaptic oscillator (EAO) that uses engineered feedback to eliminate the need for the generation and injection of the external second harmonic signal to minimize the Ising Hamiltonian. However, such implementations presently require the injection of an externally generated second-harmonic signal to impose the phase bipartition among the oscillators. Coupled electronic oscillators have recently been explored as a compact, integrated circuit- and room temperature operation-compatible hardware platform to design Ising machines.
