    • An integrated circuit for digital controlling switching noise spurs in a receiver by shifting a switching frequency (fs) to a clock frequency (fs+Δf) to move a Kth harmonic of the switching frequency (fs) is provided. The integrated circuit includes a spur controlled clock that operates the clock frequency (fs+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 (fs+Δf). Δf ranges from ( f RF - Kf s ) + BW K ⁢ ⁢ to ⁢ ⁢ ( f RF - ( K - 1 ) ⁢ f s ) - BW K - 1 , and fRF is center frequency of a received channel. None of the harmonics of the clock frequency (fs+Δf) is present in a channel of interest. The switching frequency is larger than the channel bandwidth 2BW.

    • A Force-Mode Distributed Wave Oscillator (FMDWO) that provides accurate multiple phases of an oscillation, a Force Mode Distributed Wave Antenna as a radiating element, a Force-Mode Distributed Oscillator Amplifier (FMDOA) and an array of amplifiers capable of operating as a beam forming phased-array antenna driver. Two distinct force mode mechanisms, one delay-based and the other geometry-based, utilizing inverter amplifiers, inject an oscillation on independent conductor loops or rings via transmission lines forming a differential transmission medium for the oscillation wave. Once the oscillation wave is initiated through the forcing mechanisms, the oscillations continue uninterrupted independent of any external triggering.
