Patents by Inventor James E. Vinson

James E. Vinson 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: 8064176
    Abstract: A bipolar transient clamp including a RC circuit, a clamping circuit and a breakdown circuit. The RC circuit is configured to control the rate of change of clamp. Moreover, the RC circuit is coupled between a first rail and a second rail. The clamping circuit is configured to pass a current from the first rail to the second rail. In addition, the clamping circuit is coupled to be activated by the RC circuit. The breakdown circuit is coupled between the RC circuit and the clamping circuit. The breakdown circuit is configured to increase the transient trigger voltage of the clamping circuit.

  • Patent number: 7906812
    Abstract: A tunable voltage isolation ground to ground ESD clamp is provided. The clamp includes a dual-direction silicon controlled rectifier (SCR) and trigger elements. The SCR is coupled between first and second grounds. The trigger elements are also coupled between the first and second grounds. Moreover, the trigger elements are configured to provide a trigger current to the dual-direction silicon controlled rectifier when a desired voltage between the first and second grounds is reached.

  • Patent number: 7842971
    Abstract: A silicon-controlled rectifier (SCR) device having a high holding voltage includes a PNP transistor and an NPN transistor, each transistor having both p-type and n-type dopant regions in their respective emitter areas. The device is particularly suited to high voltage applications, as the high holding voltage provides a device which is more resistant to latchup subsequent to an electrostatic discharge event compared to devices having a low holding voltage.
