Abstract

The application discloses a voltage amplitude high-frequency overshoot detection system and method, the system includes four parts: a filtering module, a superposition module, a waveform transformation module and a detection module. The method comprises: obtaining a high frequency overshoot signal, filtering out the positive value of the upper overshoot signal and the negative value of the lower overshoot signal in the high frequency overshoot signal; combining the upper overshoot voltage and the upper overshoot voltage of the filtered high frequency overshoot signal The absolute value of the lower overshoot voltage is obtained to obtain the combined high-frequency overshoot signal; the waveform of the combined high-frequency overshoot signal is transformed into a square wave with a set pulse width and a set amplitude, and the pulse width of the square wave Greater than the pulse width of the high-frequency overshoot signal; the square wave is detected. Through the present application, the accuracy of the detection result of the high-frequency overshoot signal can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of circuit voltage overshoot, in particular to a voltage amplitude high-frequency overshoot detection system and method. Background technique [0002] Overshoot is a common phenomenon in circuit design. The types of overshoot include: upper overshoot and lower overshoot. Among them, the upper overshoot means that the peak voltage exceeds the highest value of the voltage rating, and the lower overshoot means that the voltage of the valley is lower than the lowest value of the voltage rating. High-frequency overshoots generally refer to momentary shocks with very short periods and very short duty cycles. Overshoot often occurs at the moment when the circuit is powered on and off, or when there is impedance mismatch in the link to generate reflected ringing, overshoot will greatly reduce the service life of components, which is very unfavorable to components in the circuit. Therefore, how to detect ...
