hi,everyone:
I'm doing a Complex BPF,but I don't know whether it is stable？How to determine its stability?
I have done the transient simulation with a input of step signal，there is a ringing at the output, but I think the reason is large capacitances' charging in the circuit.
Meanwhile, I have done the stb simulation with the cmdmprobe,，
the schematic diagram:
the result(from left to right):
The first cmdmprobe result:
The second cmdmprobe result:
The third cmdmprobe result:
The fourth cmdmprobe result:
