how to calculate the feedback factor for a capacitive feedback opamp?
 

Re: feedback factor..

1. Open the feedback loop from a proper location in the loop
2. Apply a test signal
3. Measure the output
4. Work out the open loop gain by dividing the output to the input
5. Divide the open loop gain by the gain of the amplifier proper.

Note that since thefeedback loop is capacitive, the openloop gain should be obtained in a transfer function form.
