The bolometric sensing circuit includes a pixel array comprising pixels, each pixel comprising a sensor configuration to comprise a light receiving portion to convert incident photons into heat and a sensing portion integrated with the light receiving portion and having a resistance varying according to the converted heat; an output portion to output a common mode voltage that represents a voltage of the sensing portion from which accumulated heat has been removed in response to a heat removing voltage to thermally reset the sensing portion, and output a sensed voltage that represents a voltage of the sensing portion which has accumulated heat for an integration period after being thermally reset; and a processor to subtract the common mode voltage from the sensed voltage to produce a signal voltage that represents a change in resistance of the sensing portion due to the heat accumulated for the integration period.
