Macromodel of electro-thermal feedback for nonlinear microbolometers

Recent simulation challenges for microsensors in parallel with the development of new technology, new device configuration and applications are attempting to break the static and several simulation means, by using lumped low-order models of device behavior across multiple coupled energy domains. The lumped low-order models, namely macromodels, can help designers both by automating complex sets of related tasks and by providing rapid computational prototyping at critical points in the design cycle [1]. The study aims was to propose a macro model for nonlinear microbolometers to solve the electro-thermal feedback effect of the tiny probe current when measuring. Circuit simulator SPICE was chosen for the framework of simulation, because of the easily integrated with the associated readout circuit.
