Abstract: Overvoltage protection circuits are provided. In some embodiments, an overvoltage protection circuit includes a first diode made of a first semiconductor material having a bandgap width greater than that of silicon. A second diode is included and is electrically cross-coupled with the first diode. The second diode is made of a second semiconductor material different from the first semiconductor material.

Abstract: An acoustic galvanic isolation device includes a substrate capable of transmitting an acoustic wave. A first network of vibrating membrane electroacoustic transducers is arranged on a first surface of the substrate. A second network of vibrating membrane electroacoustic transducers is arranged on a second opposite surface of the substrate. An effective thickness of the substrate exhibits a gradient between the first and second surfaces with respect to propagating the acoustic wave.

Abstract: A data transmission device includes a coder configured to code the data into a multifrequency signal. A first array of ultrasonic transducers with a vibrating membrane is disposed on a first surface of a wafer. The first array configured to convert the signal into a multifrequency acoustic signal propagating in the wafer. A second array of ultrasonic transducers is disposed on a second surface of the wafer. The second array includes at least two assemblies of vibrating membrane ultrasonic transducers having resonance frequencies equal to two different frequencies of the multifrequency signal.
Abstract translation: 数据传输设备包括被配置为将数据编码为多频信号的编码器。 具有振动膜的第一阵列超声换能器设置在晶片的第一表面上。 第一阵列被配置为将信号转换成在晶片中传播的多频声信号。 超声波换能器的第二阵列设置在晶片的第二表面上。 第二阵列包括具有等于多频信号的两个不同频率的谐振频率的振动膜超声换能器的至少两个组件。
