A CMOS ROIC (ReadOut Integrated Circuit) for IRFPA (InfraRed Focal Plane Array) detector is a key component in uncooled thermal imaging systems. For a good IR (InfraRed) detector, low noise ROIC is needed. In this paper, a low noise CMOS OP-AMP for ROIC circuit of the 32×32 IR bolometer detector has been designed. HSPICE simulation results with a 0.35 ㎛ CMOS technology are unit gain bandwidth of 12.8 ㎒, 89 ㏈ open loop gain, 8 V/㎛ slew rate, 600 ㎱ settling time and 67° phase margin.
