Patents by Inventor Brent R. Den Hartog

Brent R. Den Hartog 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: 10211205
    Abstract: A circuit component comprises a row of transistors. The row may contain a first active FET with a source region and a drain region. The row may also contain a first active dummy FET that shares the source region and that also has a diffusion region. The row may also contain a second active FET and a second active dummy FET, positioned such that the active dummy FETs are located between the active FETs on the row. The row may also have an end positioned such that the first active dummy FET is between the end and the first active FET. A supply of current may be electrically connected to the source diffusion regions. A load region may be electrically connected to the drain region. The first active FET and the first active dummy FET may have gates that share a voltage source or that have their own voltage source.

  • Patent number: 10079595
    Abstract: Certain aspects of the present disclosure are directed to a circuit for driving a signal at an output node. The circuit generally includes a voltage divider network having a first terminal coupled to the output node. The circuit also includes a first transistor having a gate coupled to a second terminal of the voltage divider network and a plurality of transistors. A gate of each of the plurality of transistors may be coupled to a respective tap node of the voltage divider network, and the plurality of transistors may include a third transistor having a source coupled to a drain of the first transistor. The circuit may also include a second transistor coupled to the first transistor and having a gate coupled to an input node of the circuit.
