我们最近提出了一种多相振荡器，利用周期性脉冲序列产生和传播的谐振隧穿二极管（RTD）振荡器，其中每个建立通过有损电感器的邻居到邻居的耦合在一个封闭的一维晶格。在这项工作中，我们开发的设计准则的偏置依赖的振荡频率通过基于准连续模型的晶格的分岔分析。然后，我们使用时域有限差分法在全波方案中模拟晶格，并验证亚毫米波频率的多相振荡。最后，在MHz频率下使用隧道二极管代替RTD进行了几次实验观察，以验证晶格中脉冲序列的几个同步特性，包括脉冲序列的方向指定传输及其在多相振荡器中的应用。
We recently proposed a multiphase oscillator utilizing a periodic pulse train generated and propagated in a closed one-dimensional lattice of resonant-tunneling diode (RTD) oscillators, each of which establishes the neighbor-to-neighbor coupling through lossy inductors. In this work, we develop the design criteria for the bias dependence of oscillation frequency through the bifurcation analysis based on the quasi-continuous model of the lattice. We then model the lattice in the full-wave scheme using the finite-difference time-domain method and validate the multiphase oscillation in submillimeter-wave frequencies. Finally, several experimental observations conducted in MHz frequencies using tunnel diodes in place of RTDs are presented to validate several synchronization properties of the pulse train in the lattice including the direction-specified transmission of pulse train and its application to the multiphase oscillator.
