Paper Abstract

The uncooled thermal bolometer is preferred for a thermal imager because of its low cost, high reliability and high performance. The design principle of readout circuits for two-dimensional microbolometer arrays is introduced in this paper. Then the problems occurring during the progress when the signal is read out for a larger scale array are analyzed and the resolved method is introduced. Otherwise, the reason why the form of bi-CMOS circuit is more suitable for the microbolometer readout circuit is explained in the paper. At the end of the paper the nonuniformity of the circuit is simply described.
