  • Dark current mitigation with diffusion control
    Patent number: 10090426
    Abstract: A photosensor device for reducing dark current is disclosed. The photosensor device includes a photon absorbing layer and two or more photosensor diffusions in said absorbing layer. The photosensor diffusions in the absorbing layer have edges of their diffusions separated in said absorbing layer by less than two minority carrier diffusion lengths. The photosensor device also includes in one embodiment one or more diffusion control junction diffusions in the absorbing layer and in proximity to the photosensor diffusions. In another embodiment the photosensor diffusions are selectively biased to operate as photosensor diodes or as diffusion impediments.
    Type: Grant
    Filed: May 5, 2015
    Date of Patent: October 2, 2018
    Assignee: Trustees of Boston University

  • Active bias for radio frequency power amplifier
    Patent number: 5570065
    Abstract: A transceiver (100) includes a radio frequency power amplifier (116) which is biased by an active bias circuit (110). Active bias circuit (110) provides a low cost bias circuit for amplifier (116) which adjusts the bias over changes in temperature and supply voltage levels to provide a constant output power. A set of control inputs (122-126) coming from controller (108) provide for power output level adjustment for the amplifier (116) in a frequency modulated (FM) environment and for both power and modulation level adjustments in an amplitude modulated (AM) environment.
