A spread spectrum clock generator which includes a pulse train generator circuit and a modulating circuit configured to produce a modulating signal relating to a time derivative of an output of the pulse train generator circuit. In one embodiment the modulating circuit includes a active differentiator circuit and in another embodiment the modulating circuit includes a passive differentiator circuit. A modulator is included which is configured to produce a spread spectrum clock output which is frequency modulated by the modulating signal. |
