Using Multisim, I try to simulate the Differential Audio Phase Shifter circuit from:
http://electropub.files.wordpress.c...-4-coils-wrapped-around-a-ferrite-toroid1.pdf
I simulate just a single channel with 10k resistors.
When running the simulation, Multisim complains about a convergence issue, and wants to automatically solve it. It is able to solve that issue. I have no idea what this convergence issue is about.
The problem is that the output sine waveform is distorted as shown on one of the attached screenshots.
If I change all resistors to 1uohm, I get a nice sine waveform at the output (unshifted).
How can I change this circuit to get a 90 degree phase shift, and proper sine waveforms (with two channels)?
