This paper describes a new CMOS readout circuit, which makes the microbolometer focal plane array have low spatial noise over a wide operating temperature range without a thermoelectric cooler. The readout circuit corrects the nonuniformity of each microbolometer pixel by the proposed self-bias equalization technique. The proposed readout circuit adopting the self-bias equalization has a feedback loop that makes the readout circuit find the bias voltage for the correction of nonuniformity by itself. The proposed circuit was fabricated using a 0.35-mu m standard CMOS process. The measured results of the fabricated chip show that the spatial noise is less than the allowed spatial noise for the equivalent temperature difference of 50 mK over a wide operating temperature range.
