创建快速线路瞬变

其输入供应的快速瞬态集成电路的反应往往是重要的测量，以。如果下测试 （DUT） 的设备是一种微功率设备，并且不需要输入的电容，只需用 50 ω 终止函数发生器驱动器电源供应的输入。不过，由于目前的需求和电容的增加，这不再提供可接受的结果。

APPLICATION NOTE 869
Creating Fast Line Transients
An integrated circuit's response to fast transients on its input supply is often an important measurement to take.
If the device under test (DUT) is a micro-power device and doesn't require an input bypass capacitor, simply
drive the power-supply input with a 50 terminated function generator. However, as the current requirements
and capacitance are increased, this no longer provides acceptable results.

One solution to obtaining this fast transient into large capacitive loads is to make an open-loop buffer. B
