The sensitivity is tested by vacuum chamber,BR500 Blackbody radiator and MSO-X 2022A Oscilloscope,as shown in Fig.8.The chip is placed in the vacuum chamber with10 Pa pressure.BR500 Blackbody radiator is set at different temperatures,from313 K to 353 K with 10 K increment per step,MSO-X 2022A Oscilloscope measures the corresponding output voltages under blackbody radiation when the chip is provided by a constant current of 10μA.Table 2 shows the measured result,whereΔT is the difference between the blackbody temperature and the ambient temperature,ΔV is the corresponding signal voltage.The mean sensitivity is 19.1μV/K.
