However, the Bode plotter does not respond to this.

Please consider this zero-frequency IF circuit from my Living Analog blog entitled, Zero frequency IF.įor the input V3, at the same frequency as the local oscillator represented by V1 and V2 at 1 MHz, the signal output at the junction of R3 and R4 replicates the signal input. This is great, but there is a SPICE booby trap waiting for the unwary user of the Bode plotter.
