论文摘要
纳米振荡器设备正在越来越关注，这是基于耦合振荡器开发新型节能计算系统的先决条件。在这里，我们引入了一个高度可扩展的，可调节的纳米振荡器，该纳米振荡器由一个卵子阈值开关（OT）和一个场效应晶体管（FET）组成。提出的是，所提出的设备显示出可调节的固有频率（F_ {nat}）的振荡行为，这取决于应用于FET的栅极电压。此外，在少量的周期性输入下，观察到，当f_ {in} 〜f_ {nat} f_ {in} 〜f_ {nat}时，设备的振荡频率（f_ {osc}）被锁定到输入的频率（f_ {in}）时，展示了所谓的同步现象。它还使用电路模拟显示了组合振荡器网络的相位锁定，其中振荡器之间的相位关系可以通过耦合强度控制。这些结果表明，所提出的设备有望在基于振荡器的计算系统中应用。
Nano-oscillator devices are gaining more and more attention as a prerequisite for developing novel energy-efficient computing systems based on coupled oscillators. Here, we introduce a highly scalable, frequency-tunable nano-oscillator consisting of one Ovonic threshold switch (OTS) and a field-effect transistor (FET). It is presented that the proposed device shows an oscillating behavior with a natural frequency (f_{nat}) adjustable from 0.5 to 2 MHz depending on the gate voltage applied to the FET. In addition, under a small periodic input, it is observed that the oscillating frequency (f_{osc}) of the device is locked to the frequency (f_{in}) of the input when f_{in} ~ f_{nat}, demonstrating the so-called synchronization phenomenon. It also shows the phase lock of the combined oscillator network using circuit simulation, where the phase relation between the oscillators can be controlled by the coupling strength. These results imply that the proposed device is promising for applications in oscillator-based computing systems.
