Hi,
I designed an SC integrator. I used PAC to find the gain and I got it. How should I get the bandwidth of the circuit. In Kundert's paper about simulating SC filter, he mentioned on page 15 to use PXF analysis to find the bandwidth. It did not work for me. Any idea how can I find the bw?
 

com'on guys someone must know this? please help
 

Hi
Could you please specify more clearly?
The PXF analysis is almost the same as XF analysis.

You can plot gain diagram (in dB) , and where the frequency of DCgain(max)-3dB is your BW.
