Ashok Kumar Verma 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).

  • Symmetrical, direct coupled laser drivers
    Patent number: 9209599
    Abstract: Symmetrical, direct coupled laser drivers for high frequency applications. The laser drivers are in integrated circuit form and use a minimum of relatively small (low valued) external components for driving a laser diode coupled to the laser driver through transmission lines. An optional amplifier may be used to fix the voltage at an internal node at data frequency spectrum to improve circuit performance. Feedback to a bias input may also be used to fix the voltage at the internal node. Programmability and a burst mode capability may be included.
    Type: Grant
    Filed: March 2, 2015
    Date of Patent: December 8, 2015
    Assignee: Maxim Integrated Products, Inc.
