Abstract
A system and a method for modulating an input signal are provided. The system includes a fractional-N phase locked loop (PLL) for frequency multiplying the input signal by a multiplication factor to generate an output signal. The fractional-N PLL includes an input signal path and a feedback signal path. The system includes a controllable delay line for inserting a linearizing tone into the input signal path or the feedback signal path of the fractional-N PLL.
