A Low Power High Output Frequency Two-stage Output Buffer for 2720×2704 Infrared Focal Plane Array

This paper presents a low power high output frequency readout integrated circuit(ROIC) for 2720 × 2704 cryogenic infrared focal plane array (IRFPA). A two-stage output buffer is proposed to reduce power consumption and improve output frequency. This ROIC has been designed and fabricated in 0.35um CMOS technology and chip size is 44mm×46mm. The ROIC implements a dynamic range of 86dB and a readout rate of 10MHz while consumes only 180mW.
