Dobson Paul Parlindungan Simanjuntak 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).

  • Oscillator system
    Patent number: 10250269
    Abstract: An oscillator system includes a voltage controlled oscillator (VCO) circuit. The VCO circuit includes an output for providing an oscillation signal and input to receive a voltage that controls the frequency of the oscillation signal. The oscillator system includes a frequency to voltage circuit that receives the oscillation signal and produces a voltage that is dependent upon the frequency of the oscillation signal. The oscillator system includes a comparison circuit including an amplifier. The amplifier includes an inverting input, a non inverting input, and an output. During a first phase of the comparison circuit, the non inverting input receives a reference voltage and the inverting input is coupled to the output of the amplifier via a switch and to a capacitor wherein the capacitor samples the voltage of the output.
