Original Abstract Submitted

a bandgap reference circuit includes: plural bipolar transistors; plural resistors; plural switches; and a feedback control circuit which includes an amplifier and a subset of the plurality of resistors. the bipolar transistors, the resistors and the feedback control circuit generate a positive temperature coefficient signal and a negative temperature coefficient signal, and generate a bandgap reference voltage according to a linear superposition of the positive temperature coefficient signal and the negative temperature coefficient signal. the bandgap reference circuit has plural variance parameters which influence a temperature coefficient and/or an offset voltage of the bandgap reference voltage. during a calibration process, the plural switches configure the bandgap reference circuit to operate in corresponding calibration configurations, wherein each of a first subset of the variance parameters is measured individually to calibrate the temperature coefficient or the offset voltage of the bandgap reference voltage.
