电流检测唤醒时间延迟该怎么办？

嗨，我有一个应用程序，我试图使用TSC103电流检测放大器准确测量降压转换器中的电感电流。不幸的是，当转换器处于脉冲频率调制模式时，通过电感器的电流降至零，并且通过振铃它甚至可以变为负。在Spice仿真中，当转换器开关再次闭合时，我看到放大器输出的延迟（参见附图，显示检测电阻器电流和读出放大器输出电压）。

这是所谓的唤醒效果的结果吗？它是真实的还是模拟模型的人工制品？
假设它是真的，可以采取任何措施来避免它吗？任何电流检测放大器都支持负Vsense吗？

Hi, I have an application where I am trying to measure accurately the inductor current in a buck converter using a TSC103 current sense amplifier. Unfortunately when the converter is in pulse frequency modulation mode, the current through the inductor falls to zero, and with ringing it can even go negative. In the Spice simulation I see a delay in the output of the amplifier when the converter switch is closed again (see attached file showing the sense resistor current and the sense amplifier output voltage).

Is this the result of a so-called waking-up effect? Is it real or an artefact of the simulation model?
Assuming it is real, can anything be done to avoid it? Do any of the current sense amplifiers support negative Vsense?
