Paper Abstract

We compare the capacitive transimpedance amplifier (CTIA) to two other IR detector interface circuits using data compiled from hybrid FPAs in various formats from 8 X 8 to 1024 X 1024. The CTIA generally offers the best overall performance characteristics including read noise as low as 27 e- at signal bandwidths compatible with TV-type frame rates, low power dissipation (in some cases significantly less than 200 nW per pixel), and sufficiently low MOSFET self-emission for background-limited sensitivity at scene backgrounds significantly less than 109 photons/cm2- s. The alternative schemes should, however, be considered especially when very high transimpedance is needed at moderate bandwidths or when radiometric linearity is not required.
