Abstract
A method for mitigating interference from a switched-mode power supply begins by comparing a channel of interest of a plurality of channels with a switching rate of a switch-mode power supply. The method continues when the channel of interest compares unfavorably to the switching rate by adjusting the switching rate of the switch-mode power supply until the channel of interest compares favorably to the switching rate.
Claims22
A method for mitigating interference from a switched-mode power supply comprises:
- comparing a channel of interest of a plurality of channels with a switching rate of a switch-mode power supply;
- and
- when the channel of interest compares unfavorably to the switching rate, adjusting the switching rate of the switch-mode power supply.
A method comprises:
- determining a channel of interest of a plurality of channels;
- and
- establishing a switching rate of a switch-mode power supply based on the channel of interest.
A radio comprises:
- receiver section operably coupled to convert a radio signal into a baseband signal, wherein the radio signal corresponds to a channel of interest of a plurality of channels;
- a switched-mode power supply operably coupled to convert a source voltage into a power supply voltage at a switching rate, wherein the receiver section is at least partially powered by the power supply voltage;
- a processing module operably coupled to:
- compare the channel of interest with the switching rate of the switch-mode power supply;
- and
- when the channel of interest compares unfavorably to the switching rate, adjust the switching rate of the switch-mode power supply.
