AI Technical Summary

Problems solved by technology

Using a resistor network to collect power supply glitch voltage not only has DC power consumption, but also the resistor network can only collect low-frequency signals on the power supply, and cannot achieve the same ratio of high-frequency signal collection on the power supply, which is limited by the voltage amplitude and frequency of the glitch attack. When the detection circuit of the structure is working normally, it will also be affected by the DC value of the detected voltage
