Abstract
A sensing device includes a pair of infrared sensors comprising respective temperature-sensitive transistors, which are configured to generate respective output signals in response to incident thermal radiation, and which are coupled together in a differential circuit topology that includes at least one differential amplifier that follows the temperature-sensitive transistors, so as to amplify a difference between the respective output signals.
