Chip-to-chip communication method and system for wireless testing

芯片间的通信问题近年来得到了广泛的关注。本研究的目的是调查可能用于这些目的的振荡器和振荡系统与集成变压器。当开始测试的命令从测试器芯片发送到被测芯片，然后关于测试结果的信息返回到测试器时，预期结果对于无线测试将特别有用。 这项研究的想法是基于两个已知的实验事实。 首先，在具有在振荡槽中使用的集成Transformer初级的正弦振荡器中，可以使用次级的负载的强烈变化来改变和控制振荡幅度和频率。这种负载影响通常被认为是一种寄生效应。然而，Transformer可以被认为是两个相互作用的天线。然后，所描述的效果可以用于经由隔离间隙从位于一个芯片上的振荡器传输信息，并且其中初级被用作发射天线，次级被用作位于另一个芯片上的接收天线，并且连接到可变负载或所需的电子电路。 其次，在不同功率的耦合振荡系统中，一个系统成为主系统，另一个系统成为从系统：同步振荡的频率和幅度由较大功率的系统定义和控制。本研究的目的是调查这种行为时，系统实现的电子电路和可能的应用，这种电路的芯片到芯片的通信在无线测试。 这两种现象在芯片间通信中的应用从未被考虑过，但它可能在其他领域具有实用价值。本研究的经济价值也可用于传感、无线通信和芯片制造。

The problem of chip-to-chip communication obtained recently a lot of attention. The purpose of this research is to investigate possible using for these purposes oscillators and oscillating systems with integrated transformers. The expected results will be particularly useful for wireless testing when the command to start testing is transmitted from a tester chip to the chip under test and then the information on testing results returns back to the tester. The idea of this research is based on two known experimental facts. First, in a sinusoidal oscillator with the integrated transformer primary used in the oscillation tank one can change and control the oscillation amplitude and frequency using strong variations of the load of the secondary. This load influence is usually considered as a parasitic effect. Yet a transformer can be considered as two interacting antennas. Then the described effect may be used for transmission of information via isolation gap from the oscillator located on one chip and where the primary is used as transmitting antenna to the secondary used as receiving antenna located on another chip and connected to a variable load or to a required electronic circuit. Second, in coupled oscillating systems of different powers one system becomes master and another becomes a slave: the synchronous oscillations frequency and amplitude are defined and controlled by the system of larger power. The intention of this research is to investigate this behavior when the systems are realization by electronic circuits and possible application of such circuits for chip-to-chip communication in wireless testing. The application of these two phenomena to the chip-to-chip communication was never considered, and it may be of utility in other areas. The economic value of this research can be also used in sensing, wireless communication, and chip fabrication.
