Paper Abstract

The analysis of dynamics of self-heating and electrical signals in pulse biased microbolometers connected in different modes (constant voltage and constant current modes and also Wheatstone bridge) is presented. Analytical expressions for determination of thermal parameters (thermal time constant heat capacitance and thermal conductance) of thermoresistive microbolometers applicable under significant heating are derived. The experimental results are in good agreement with the theoretical analytical dependences.
