摘要: This paper presents a design model for uncooled microbolometers readout integrated circuits (ROIC). The relation between infrared focal-plane array (FPA) performance and ROIC specification limits is shown distinctly. A simple way to find optimal operating conditions certain construction also described. signal noise of the investigated in detail. reasonable estimate equivalent temperature differences microbolometer detectors can be calculated with this model. capacitor feedback transimpedance amplifier circuit treated as an example. An experimental chip based on has been designed implemented silicon using 0.5-μm CMOS technology. temporal root mean square output voltage 424 μV, which corresponds well measurement result. result demonstrates reliable prediction achievable improvements FPA by
