A validity study of an industrial SPICE-based op-amp macromodel for high-temperature simulation

Abstract : This paper evaluates the validity of an industrial SPICE-based model of an operational amplifier (op-amp) for high temperature (HT) simulation purpose. A SPICE model of a commercial op-amp, which is provided by the constructor, is simulated with PSpice. More precisely, two op-amp performance parameters (the input voltage offset and the common mode rejection ratio) are simulated and compared to measurement results. The validity of the proposed SPICE op-amp model in HT is evaluated by comparing experimental measurements to SPICE model simulations and calculating the SPICE model error. A solution to overcome the limitation of this model in HT is proposed and some references are listed.
