Hi guys, I'm trying to do a simulation of 90 degree phase shift to my square wave signal. Before this I tried to use an integrator and a comparator. But this circuit is only capable to have 90 degree phase shift for a definite frequency. That's mean for other frequencies it will have different phase shift.
So, anyone can help me with this? How to do a 90 degree phase shift for square wave with any frequency? I heard there is a digital phase shifter. But I'm not very sure about that.
Thanks:)
