Mikko J. Nasila has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Phase-locked-loop pulse-width modulation system
    Patent number: 6208216
    Abstract: A phase-locked loop applied as a phase modulator using an external analog control signal whereby a single-ended pulse-width modulated digital signal may be derived from the phase detector output, and two phase modulated square-wave digital signals may be derived from a reference oscillator and the feedback voltage controlled oscillator. The pulse width modulation and/or phase modulation in power applications can be achieved with far greater speed, precision, simplicity and economy than by existing techniques.
