摘要
This paper presents a micromachined 16 x 16 array of thermoelectric infrared sensors fabricated in a commercial CMOS IC process with subsequent bulk-micromachining on wafer-scale. Each pixel contains an integrated heater, which makes calibration and self-testing possible. Addressing circuitry and four low-noise amplifiers are cointegrated with the array on a single chip with a size of 7.4 x 12 mm(2). A thermal imager, based on the infrared sensor-array, operates in ambient air, without thermal stabilization or cooling. The thermoelectric sensor principle allows to measure DC radiation signals even without a radiation chopper. The temperature resolution achieved at 1 Hz framerate is 176 mK.
