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.

芯片到芯片交流的问题最近引起了很多关注。这项研究的目的是研究使用这些目的的振荡器和具有集成变压器的振荡系统的可能性。当将命令从测试器芯片传输到正在测试的芯片中时，预期的结果对于无线测试特别有用，然后测试结果的信息返回回到测试仪。 这项研究的想法基于两个已知的实验事实。 首先，在振荡罐中使用的积分变压器主要的正弦振荡器中，可以使用次级载荷的强大变化来改变和控制振荡振幅和频率。这种负载影响通常被视为寄生作用。然而，变压器可以被视为两个相互作用的天线。然后，所描述的效果可用于通过从位于一个芯片上的振荡器隔离间隙的隔离间隙传输信息，在该芯片上用作将天线传输到用于接收天线的二级天线，并连接到可变负载或所需的电子电路。 其次，在耦合的不同功率的振荡系统中，一个系统变为主，另一个系统成为一个从：同步振荡频率和振幅由较大功率的系统定义和控制。这项研究的目的是研究当系统通过电子电路实现并可能在无线测试中使用此类电路来实现这种行为。 从未考虑过这两种现象在芯片到芯片交流中的应用，在其他领域可能是有效的。这项研究的经济价值也可以用于传感，无线通信和芯片制造。
