1. An inductor array, comprising:
a first inductor with a first inductance, and wherein the first inductor is switched at a first frequency;
a second inductor with a second inductance that is different than the first inductance, and wherein the second inductor is switched at a second frequency that is different than the first frequency; and
a third inductor with a third inductance, wherein the third inductance is different than the first inductance and the second inductance, and wherein the third inductor is switched at a third frequency that is different than the first frequency and the second frequency.
