Patents by Inventor Jacob K. Easter

Jacob K. Easter 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).

  • Patent number: 10691151
    Abstract: A system includes a first transistor having a drain and source connected between a supply voltage and an output of a voltage regulator. A gate of the first transistor receives a first gate voltage. The system includes a second transistor having a drain and source connected between the supply voltage and the drain of the first transistor. The second transistor protects the first transistor from excessive voltage. The system includes a level shifter connected between a gate of the second transistor and a gate of the first transistor. The level shifter produces a level-shifted gate voltage for the second transistor that is based on the first gate voltage and that is proportional to an output load current output at the source of the first transistor.

  • Patent number: 10200001
    Abstract: At least one example embodiment provides a controller to sample a first signal. The first signal indicates an initial amplitude of an output signal of an oscillator circuit. The controller selects a step amount based on the first signal and a target amplitude of the output signal. The controller generates a control signal for the oscillator circuit based on the selected step amount. The control signal indicates a change in gain for the oscillator circuit according to the selected step amount.

  • Patent number: 9350059
    Abstract: Circuits and methods related to a switch having extended termination bandwidth are disclosed. A switch having an input end and an output end, and capable of being in an ON state and an OFF state, can include a termination circuit configured to yield an extended frequency bandwidth in which a desired OFF state termination impedance is provided. A termination circuit may include two or more electrically parallel resistor-capacitor branches coupled to the switch input or output end. A switch termination circuit may provide an OFF state termination impedance that is substantially equal to the switch ON state termination impedance. Also, a termination circuit may enable a desired termination impedance without sacrificing other switch performance features, including insertion loss, isolation, or VSWR difference between ON and OFF states. Also disclosed are examples of how the foregoing features can be implemented in different products and methods of fabrication.
