Abstract :
A new readout circuit involving two-step current-mode background suppression is studied for two-dimensional long wavelength infrared (2D LWIR) focal plane arrays. The simple pixel circuit has a very small skimming error of less than 0.3%, low noise characteristics for an adequate calibration range, and a long integration time of 2 ms.
