Hello - I have a bandpass filter, simulated with an AC response.
I'm using Cadence IC615, and in the calculator trying to get the -3dB points for both HPF and LPF corners.

It's a very clean filter passband (no ripples), and clean roll-offs (no P-Z doublets, etc.)

The AC sim is done well before the HPF corner and well *after* the LPF -3dB corner.

The calculator either
a) gives me an Error \n, does not evaluate waveform,
or
b) calculates one side (ie, low or high), but gives a very wrong result.

Any tricks??

thanks,
Wave

bandwidth(VF("/sim_node2") 3 "low")

Wave,

  For what it is worth bandwidth works for me.
