摘要：
A variable modulus delta-sigma modulator can generate any rational DC value with absolute accuracy. When applied in fractional-N frequency synthesis it allows for generating a series of frequencies with exact channel spacing for a given radio standard. It removes the problem of approximating frequencies and resulting constant phase drift.
