Abstract
An integrated circuit for digital controlling switching noise spurs in a receiver by shifting a switching frequency (f) to a clock frequency (f+Δf) to move a Kharmonic of the switching frequency (f) is provided. The integrated circuit includes a spur controlled clock that operates the clock frequency (f+Δf), and a DC-DC converter circuitry that includes a first power switch, and a second power switch. The first power switch and the second power switch are driven by the clock frequency (f+Δf). Δf ranges from and fis center frequency of a received channel. None of the harmonics of the clock frequency (f+Δf) is present in a channel of interest. The switching frequency is larger than the channel bandwidth 2BW.
