description In a system and method for correcting a stress-impaired signal in a circuit, a calibration circuit produces a first calibrated voltage based on a base-emitter voltage of one or more pnp transistors, a second calibrated voltage based on a base-emitter voltage of one or more npn transistors, and a voltage proportional to absolute temperature. A set of reference values are generated based on these voltages. A gain correction factor is calculated based on a function of the set of reference values and a set of temperature-dependent values, and the stress-impaired signal is corrected based on the gain correction factor.
