  • Systems and methods for controlling the voltage on the lens of electron emitter devices
    Patent number: 7102979
    Abstract: Methods for controlling the voltage on a lens of an electron emitting device are provided. A representative method includes: supplying an emitter voltage to an electron emitter in the electron emitting device, wherein a current amplitude is established; sensing the emitter voltage on the electron emitter; supplying a non-inverted input voltage to an amplifier that follows the emitter voltage; and providing an amplifier output voltage from the amplifier to the lens, wherein the amplifier output voltage corresponds to the emitter voltage at the electron emitter. Systems, devices and other methods also are provided.
    Type: Grant
    Filed: November 7, 2001
    Date of Patent: September 5, 2006
    Assignee: Hewlett-Packard Development Company, LP.
