Claim:
1. A circuit comprising: a radio frequency (RF) switch having an energy management core, wherein the energy management core includes: a charge pump; and an oscillator coupled with the charge pump, wherein the oscillator provides a clock signal to the charge pump, and the oscillator is configured to generate the clock signal at a predefined frequency based upon an input signal received by the oscillator; and a counter coupled with the oscillator, wherein the counter provides the input signal to the oscillator, and the counter is configured to provide, to the oscillator, a first signal as the input signal to cause the oscillator to generate the clock signal at a first frequency for a predefined period of time and thereafter the counter is configured to provide a plurality of other signals as the input signal to cause the oscillator to generate the clock signal at a plurality of other frequencies in a pattern, wherein:
