Abstract:
Structure and methods for a compensated bandgap reference circuit. A first integrated circuit die having a first bandgap reference circuit with a non-zero temperature coefficient; and having a first output reference signal is provided, a second integrated circuit die having a second bandgap reference circuit with a non-zero temperature coefficient that is of opposite polarity from the temperature coefficient of the first bandgap reference circuit, and having a second output reference signal is provided; an adder circuit disposed on at least one of the first and second integrated circuit dies combines the first and second output reference signals, and outputs a combined reference signal; and connectors for connecting the first and second output signals to the adder circuit are provided. Methods are disclosed for pairing integrated circuit dies with bandgap reference circuits and coupling the dies to form temperature compensated signals.
