Abstract
A non-linear spread spectrum clock generator using a linear combination may include a phase locked loop configured to receive a reference signal and generate an output signal according to the reference signal and a feedback signal that compensates for the output signal. The phase locked loop may include a divider configured to generate the feedback signal by dividing the output signal by a divisional ratio. The non-linear spread spectrum clock generator may include a non-linear profile generator configured to generate a non-linear signal by selectively outputting selected ones of a plurality of signals according to the absolute magnitudes of the signals and a delta-sigma modulator configured to receive the outputted linear ramp function and to change the divisional ratio. The signals may vary according to different linear ramp functions. The different ramp functions may include different slopes and initiation time values.
