I am using opamp OPA1664 as a voltage follower for one application. I am using a filter circuit for the output as shown below.
I have copied the circuit from some reference design. I do not have idea what the circuit at the output is. Can anyone help me understand the circuit and how to select the values for diode, transistor and resistor?
