ABSTRACT:
A microbolometer circuit includes, in accordance with an embodiment, a first microbolometer and a bias circuit, coupled to the first microbolometer, configured to provide a bias current to the first microbolometer to provide a first output signal based on a resistance of the first microbolometer. An output circuit, coupled to the bias circuit and the first microbolometer, is configured to provide an output signal based on the first output signal, wherein the bias circuit or the output circuit or both are configured to provide a varying signal level to compensate the first output signal for a change in the resistance of the first microbolometer due to the bias current increasing a temperature of the first microbolometer.
