Nonlinear cooperative behavior appears naturally in many systems, such as cardiac cell oscillations; cellular calcium oscillations; oscillatory chemical reactions, and fireflies. Such systems have been studied in detail due to their inherent properties of robustness, adaptability, scalability, and emergence. In this paper, such nonlinear cooperative behaviors are considered within the domain of electronic system design. We investigate these desirable properties in a system composed of electronic oscillators. The paper presents a series of circuit simulation results showing that self-organizing principles, which can be emulated in an electronic circuit, enable the systems to show a phase transition to synchronization, in a manner similar to those of natural systems. Circuit simulation results presented here show that the circuits are robust to the unreliable performance of the electronic oscillators and tolerant to their run-time faults. These are important findings for future engineering applications in which the system's elements are likely to be unreliable and faulty, such as in molecular- and nanoelectronic systems.
非线性协同行为自然出现在许多系统中,如心脏细胞振荡;细胞钙振荡;振荡化学反应和萤火虫。由于其固有的稳健性、适应性、可扩展性和涌现性等特性,这些系统已经得到了详细的研究。在本文中,将这些非线性协同行为考虑在电子系统设计领域内。我们在由电子振荡器组成的系统中研究这些理想特性。本文提出了一系列电路仿真结果,表明可以在电子电路中模拟的自组织原理使系统能够以类似于自然系统的方式向同步相变。本文提出的电路仿真结果表明,这些电路对电子振荡器不可靠的性能具有鲁棒性,并且对它们的运行时故障具有容忍性。这些发现对于未来的工程应用非常重要,因为在这些应用中,系统的元件可能是不可靠和有故障的,例如在分子和纳米电子系统中。
