ABSTRACT:
An arrangement and a method for providing a temperature-dependent signal. Several current sources (1, 2) are provided, which are switchably connected to one or more diodes (8). The conducting-state voltage of the diode is compared with a reference signal (Vr) in a comparator (10). A control circuit (12) controls the current sources (1, 2) so that for calibrating in each calibration step, only one of the current sources is activated and, in another calibration step, all of the current sources (1, 2) are activated. Therefore, error terms can be calculated, which allow a very exact provision of a temperature-dependent signal with respect to the matching of the current sources to each other.
