Regarding SP simulation for phase shifter (phase interpolator)
I would like to ask a question about S-Parameter (SP) simulation for phase shifter (phase interpolator) design. I am designing a 10GHz phase shifter using I/Q interpolation (so called, Cartesian phase shifter or phase rotator). In order to see the phase shift, I ran a transient simulation and it worked as expected.
However, when I ran ...
