Hello,
I read somewhere that "single-ended symmetry" improves 1/f noise
rejection for LC VCOs ... but what means "single-ended symmetry" ?
(sorry I'm no good english speaking person)
Thanks,

I think that what they mean is "full differential" and "pseudo-differential". Full differential is the case where EVERY common-mode node in the circuit is floated as virtual ground, like the common-source in a differential pair.
Pseudo-differential is when you juxtapose (to place side by side) two single-ended circuit to give you a differential circuit.
