Abstract

Various techniques are provided for implementing an infrared imaging system, especially for low power and small form factor applications. In one example, a system includes a focal plane array (FPA). The FPA includes an array of infrared sensors adapted to image a scene. A low-dropout regulator (LDO) is integrated with the FPA and adapted to provide a regulated voltage in response to an external supply voltage. The FPA also includes a bias circuit adapted to provide a bias voltage to the infrared sensors in response to the regulated voltage. The FPA also includes a read out integrated circuit (ROIC) adapted to provide signals from the infrared sensors corresponding to captured image frames. Other implementations are also provided.
