A new noise reduction circuit that suppresses noise bandwidth of the output stage is proposed for the readout circuit of an infrared detector operating at a high pixel rate. Using this circuit, it is found that the rms noise voltage of the output stage is effectively reduced from 87 to 52 µV at a pixel rate of 10 pixel/µs.
