The characteristic thermal parameters of a platinum-film microbolometer are extracted from the data of two measuring methods, A simple and accurate equivalent circuit model, along with its thermal behavior, is proposed for the device. Applying the model to simulate some device circuits results in good agreement with the experimental data, Furthermore, an effective method of ambient temperature compensation, proposed previously by our laboratory, is demonstrated both experimentally and by simulation using the same model. The established electro-thermal model therefore serves as an useful tool for SPICE simulations in the design of microbolometers.

Device parameters of thermal microsensors are essential for evaluating the sensor performances and their simulation modeling. We report an A.C. electrical method for extracting these parameters experimentally with relatively simple instrumentation. The basic parameters of resistive microsensors, the resistance, temperature coefficience of resistance, thermal capacitance and conductance, are derivable from the second harmonic signal of the output voltage induced by a sinusoidal driving current. The results obtained are compared with other methods.
