%X InGaAs shortwave infrared focal plane array (FPA) has important application in space remote sensing. In this paper, a design is presented for a low-noise InGaAs FPA readout integrated circuit (ROIC). In order to promote the signal-to-noise ratio, a new correlated double sampling (CDS) circuit is presented for eliminating KTC noise of integration capacitor (0.15 pF) in mode of integration while read. The circuit has been fabricated with 0.5-m 5V N-well CMOS process. Test results show that ROIC noise is 1.710-4 V and dynamic range is above 80 dB, working well after interfaced with InGaAs detectors.
