Patents by Inventor Daniel K. Hartman

Daniel K. Hartman 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).

  • High-speed, low-power crossbar switch
    Patent number: 6965299
    Abstract: In a crosspoint switch, both input buses and output buses are driven at low swing. Self-timed, differential, push-pull, low swing driver circuits drive the input buses and are provided in the crosspoints to drive the output buses. Clocked, regenerative sense amplifiers are provided in crosspoints and at outputs of the data buses.
    Type: Grant

  • High-speed, low-power inter-chip transmission system
    Patent number: 6614268
    Abstract: In an integrated circuit, a data link relies on low swing differential signals. A push-pull driver circuit and a receiver circuit are both clocked from a common on-chip clock. A driver circuit includes an H-bridge of NMOS transistors and a line-to-line precharge circuit which reduces the power requirements of the circuit. A clocked repeater within the link may itself comprise a clocked receiver and an H-bridge driver with line-to-line precharge.
