ABSTRACT:
Method and system for periodically measuring the junction temperature of a semiconductor device. The junction exited by at least two sequential predetermined currents of different magnitudes. The voltage response of the junction to the at least two currents is measured and the temperature of the junction is calculated, while substantially canceling ohmic effects, by using the voltage response and a correction factor obtained by periodically. Whenever desired, the junction is exited by a set of at least four sequential different currents having known ratios. The voltage response to the set is measured and the correction factor is calculated by using each voltage response to the set.
