  • High sensitivity photodetector with high-gain transimpedance amplifier
    Patent number: 11378447
    Abstract: One aspect of the present technology relates to a device. The device includes a sensor having an anode and a cathode. An operational amplifier (op-amp) having a single-ended output terminal, a non-inverting input, and an inverting input, is operatively coupled to one of the anode or the cathode of the sensor by the inverting input. A feedback resistor having a resistance of at least approximately one giga-ohm (1 G?) is operatively coupled between the single-ended output terminal and the inverting input of the op-amp. A grounded field shunt is positioned adjacent to the feedback resistor. The op-amp, grounded field shunt, and feedback resistor are disposed within an electrical shield enclosure. The single-ended output terminal of the op-amp terminates outside of the electrical shield enclosure.
