Abstract :
A low-noise readout architecture for uncooled microbolometer focal plane arrays is described. A 40times30 uncooled microbolometer focal plane array based on the low-noise ROIC was implemented on silicon using a 0.5 mum CMOS technology. Total output noise voltage is 260 V RMS. Experimental values of voltage responsivities of 3.98 105 V/W on average at 1 Hz modulation frequency have been achieved.
