摘要：When we use oscilloscopes to observe power waveforms, inverter circuit waveforms and other high voltage signal waveforms through conventional passive probes, there are many risk factors because of grounding problem. However, we can use high voltage differential probe to solve these problems. The key technology of differential probe is to design high frequency differential isolation circuit [1]. This paper designs a high-speed differential signal transmission circuit with theoretical analysis, simulation and testing, enabling the transmission frequency up to 10MHz.
