Patents by Inventor Gottfried Fraiss

Gottfried Fraiss 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: 7095258
    Abstract: Circuitry is disclosed for controlling the slope of rising and falling edges of a signal. The circuitry includes a ramp signal generator that receives an input signal and that generates a trapezoidal signal based on the input signal, and a circuit array that receives the trapezoidal signal and that generates control signals based on the trapezoidal signal. Output transistors have gates that receive a set of the control signals. The output transistors include a top transistor and a bottom transistor. The top transistor has a source connected to a supply potential and a drain connected to an output. The bottom transistor has a source connected to a reference potential and a drain connected to the output. The top transistor and the bottom transistor are gated by the control signals to control a shape of an edge of an output signal at the output.
