Hi, Sugar,
I understand that you want to have an intuitive time domain analysis. But your statement is wrong. At any time, the delta phi/delta t varies as the control voltage varies. So it is not a sine wave strictly. Anyway, it is still a periodic signal, then it is combined by 3 components, ω0-ω1, ω0, ω0+ω1. The result can be derived using fouries series or simple maths as that in Razavi's book.
Best regards, Yawei
