  • Patent number: 4764732
    Abstract: There is disclosed an amplifier device for use with a photodetector for amplifying wave energy signals received by the photodetector and converted into electrical signals. The amplifier device includes a first amplifier having its input connected to a junction between the photodetector and first and second photodetector load impedances. A negative feedback amplifier is connected to the output of the first amplifier. The negative feedback amplifier provides a feedback voltage to the first load impedance when in its first mode of operation and effectively reduces the voltage feedback to the first load impedance when in its second mode of operation. A switching device is provided to effectively switch the second load impedance in and out of circuit with the photodetector to effectively change the photodetector load impedance and alter the bias voltage to the feedback amplifier.
