Abstract
A circuit arrangement for generating light-dependent and temperature-dependent signals has a number of first and second sensor elements, which generate a number of first and second electrical signals. The first and second electrical signals depend on electromagnetic radiation impinging on the circuit arrangement. The first sensor elements are designed to generate the first electrical signals in a manner dependent on electromagnetic radiation from a first wavelength range which comprises a substantial part of the visible light. The second sensor elements are designed to generate the second electrical signals in a manner dependent on electromagnetic radiation from a second wavelength range which predominantly comprises infrared radiation. The first wavelength range overlaps the second wavelength range and it therefore also comprises infrared radiation.
