  • Amplifier and array for measuring small current
    Patent number: 9086400
    Abstract: An array of electrochemical detectors includes an array of electrodes that provide current responsive to oxidation events. Each electrode is coupled to a transistor, an amplifier coupled to an input of the transistor and having a feedback loop coupled to the electrode and providing a bias voltage to the electrode, an integrating capacitor coupled to the transistor operable to integrate charge from the electrode, and a reset switch coupled to the integrating capacitor. The amplifier may have a shared stage with other detectors. A shared buffer circuit may also provide a sampled output from multiple detectors.
    Type: Grant
    Filed: November 25, 2008
    Date of Patent: July 21, 2015
    Assignee: Cornell Research Foundation, Inc.
    Inventors: Bradley A. Minch, Sunitha Bandla Ayers, Manfred Lindau
