Abstract

A circuit for readout of LWIR photodiode in area FPA is suggested and simulated. It is expected, that the combination of a dynamic current mirror and the buffered direct injection input (DCM-BDI) will be capable of a hundred-fold dark current and background current suppression, and perfect, within a few millivolt over FPA, detector biasing. The estimates are made of which improvement in detectivity the novel readout scheme can bring. To realize fully the benefits of the DCM-BDI readout, the buffer amplifier 1/f-noise should be made as small as 100 nV/Hz^1/2 at 1 Hz.
