Abstract: An important task in the design of sensor devices, including thermography, is the development of systems that provide accurate processing of input data, as well as their conversion into a digital signal. The results of application of the generalized electrical (compact) model of the thermal uncooled detector bolometric type (microbolometer) implemented in the Verilog-A hardware description language, which takes into account the peculiarities of the design and materials used for its fabrication, in the design of circuit and topological solutions of the integrated circuit for reading data from a matrix of detectors located in the focal plane, using the TSMC 0.18 $\mu$m design library, are presented.

Keywords: uncooled thermal detector of bolometric type, microbolometer, infrared detector, vanadium oxide, matrix in the focal plane, readout integral circuit, modeling.
