Abstract:
1. A method for stabilizing a post-thermal-trimming resistance of a thermally isolated resistor made from a thermally mutable material, the method comprising: generating at least one heating signal, each one of said at least one heating signal having an initial amplitude corresponding to an annealing temperature, a slope corresponding to a given cooling rate and a duration corresponding to a given cooling time; and applying said at least one heating signal to one of said thermally isolated resistor and a heating device in heat transfer communication with said thermally isolated resistor, after a trimming process, in order to cause said resistor to cool gradually in response to each of said at least one heating signal and in accordance with said given cooling rate, said given cooling rate being slower than a passive cooling rate determined by a natural thermal time constant associated with the thermal isolation and thermal inertia of the resistor.
