Abstract
A method for determining a temperature of a pixel; wherein the method includes supplying, by a current supply circuit and to the pixel, a bias current of a first value during a first period; changing, by the current supply circuit, a value of the pixel bias current to a second value; supplying, by the current supply circuit and to the pixel, a bias current of a second value during a second period; wherein the first value differs from the second value; reading, by a readout circuit that is coupled to the pixel, at a first point of time, a first output voltage of the pixel; wherein the first point in time occurs during the first period or the second period; and reading, by the readout circuit, at a second point of time that differs from the first point in time, a second output voltage of the pixel; wherein the second point in time occurs during the first period or the second period; wherein a difference between the first and second output voltage is indicative of a temperature of the pixel.
