Apparatus for and method of providing long integration times in an IR detector |
摘要 |
Apparatus for and method of increasing the effective integration time, and, hence, reducing the noise bandwidth of a photodetector. The current output of the photodetector is converted to a voltage signal in a low pass filter. The low pass filter is preferably implemented as a switched capacitor filter.
