Abstract

This paper presents a new Read_out IC (ROIC) that uses two shared capacitances for integral and sampling. At similar power consumption and chip area, this ROIC architecture achieves a higher frame rate compared with the conventional architecture. A 384×288 uncooled microbolometer focal plane array (FPA) based on the proposed circuit was implemented on silicon using a 0.5 μm CMOS technology. Measurements show the proposed architecture enables the frame rate increase of 6.8% using the same master clock.
