摘要
A method for reducing the fractional spurious in a fractional N-PLL oscillator comprising a phase comparator having nonlinear elements and a variable frequency oscillator that responds to the low frequency component of output signals of the phase comparator and with which reference signals and signals obtained by dividing the output signals of the variable frequency oscillator are input to the phase comparator, wherein the oscillation frequency component of the variable frequency oscillator is eliminated from the signals input to the phase comparator and the fractional spurious is thereby reduced. The oscillation frequency component of the variable frequency oscillator is eliminated using a gate in the drawings.
