This paper presents and briefly discusses recent observations of dynamics associated with isolated generalized bipolar transistor cells. A mathematical model of this simple system is considered on the highest level of abstraction such that it comprises many different network topologies. The key property of the analyzed structure is its bias point since the transistor is modeled via two-port admittance parameters. A necessary but not sufficient condition for the evolution of autonomous complex behavior is the nonlinear bilateral nature of the transistor with arbitrary reason that causes this effect. It is proved both by numerical analysis and experimental measurement that chaotic motion is miscellaneous, robust, and it is neither numerical artifact nor long transient motion.
本文介绍并简要讨论了与隔离式广义双极晶体管单元相关的动力学最新观测结果。在最高抽象层次上考虑了这个简单系统的数学模型，使得它包含许多不同的网络拓扑结构。由于晶体管是通过二端口导纳参数建模的，所以所分析结构的关键特性是其偏置点。晶体管具有非线性双边特性（由任意原因导致这种效应）是自主复杂行为演化的必要但不充分条件。通过数值分析和实验测量都证明了混沌运动是多样的、稳健的，它既不是数值假象也不是长时间的暂态运动。
