PSPICE Circuit Simulation of Microbolometer IRFPA Unit Cell Using Sub-circuit Model of Microbolometer
In this paper, the microbolometer sub-circuit model has been used in Wheatstone bridge readout configuration to study the application of the model for readout circuit design. The sub-circuit model has been used as both active as well as blind device. The effect of the varying input radiation is analyzed on the integration capacitor and at the output of the bridge. The temperature node of the microbolometer has also been analyzed to see the heating effect of bias current on the device.
