Customer is using LM7321 to bias some RF amplifiers and is observing large output oscillations. They selected the LM7321 because of its ability to handle capacitive loads without a RISO resistor. Adding a resistor is not desired in this application. The bias circuit consists of two LM7321, with the output of the first feeding into the second with a resistor divider. See attached for basic circuit and captured oscillations.
Amplifiers are powered from 0V and -7.9V. Spice simulation does not show this response, but maybe the model is not accurate for this type of load.
I have more data that I can provide if you contact me offline.
