Spectrum spreaders including tunable filters and related devices and methods

摘要

Embodiments herein relate to a spectrum spreader comprising a signal conductor configured to receive a clock signal having a clock signal frequency. The spectrum spreader further comprises a tunable filter coupled to the signal conductor wherein the tunable filter is configured to spread a frequency of the clock signal responsive to a control signal to provide a spread spectrum clock signal wherein a frequency of the spread spectrum clock signal is spread relative to the clock frequency wherein the tunable filter comprises an inductor-capacitor (LC) band pass filter.
