  • Electro-magnetic interference reduction using opposing field transmitter
    Patent number: 8643446
    Abstract: An electronic system that partially or perhaps even fully mitigates the effects of EMI by having a dedicated antenna circuit for carrying an antenna signal that is not used for signal processing in the functional circuit, but is instead used to emit electromagnetic radiation that at least partially offsets EMI emitted by the operation signal of a functional circuit. An antenna signal generation circuit generates the antenna signal and asserts the antenna signal on the antenna circuit. The ante a signal has the characteristic such that when the antenna signal is applied to the antenna circuit, the resultant emitted electromagnetic radiation at least partially offsets electromagnetic interference emitted by the functional circuit.

  • USB system with spread spectrum EMI reduction
    Patent number: 7953175
    Abstract: A method for applying spread spectrum noise reduction techniques to USB specifically USB2.0 communications systems includes the step of generating a base (seed) frequency for the USB system, modulating the base (seed) frequency with a spread spectrum (SS) characteristic, and utilizing (as-is, not modified) the existing ASIC that multiplying the now modulated base (seed) frequency to generate the USB standard frequency signaling rate of 480 MHz with the SS characteristic within the USB standard specification for frequency deviation.
