Abstract

A calibration method for a temperature sensor of an electronic device, wherein the electronic device comprises a temperature sensor, an electronic circuit configured to emit a predetermined amount of heat, and a control circuit. The method comprises steps of determining (Si) a first parameter value of a parameter of the electronic device that is representative for a first temperature of the electronic device; controlling (S2, S3), by the control circuit, the electronic circuit to emit the predetermined amount of heat for a predetermined time; determining (S4) a second parameter value of a parameter of the electronic device that is representative for a second temperature of the electronic device after the predetermined time has elapsed, calculating (S5), by the control circuit a gradient based on the determined first parameter value, the determined second parameter value, the first temperature and the second temperature, and determining a gain error based on the calculated gradient.
