  • Detection circuit for maintaining constant signal transfer characteristics of a light-sensitive detector
    Patent number: 5296697
    Abstract: A variable impedence photodiode detector circuit for use in detecting signals in the infrared (IR) includes circuitry to maintain a constant reverse bias voltage on the photodetector to maintain the best signal transfer characteristics regarding frequency response, analog bandwidth, sensitivity, output current range, and signal-to-noise ratio over an operating range from total darkness to maximum daylight. A series current source varies the current to the photodiode in response to variations in detector impedence.
