Abstract :
A very low temperature coefficient (<; 1 ppm/°C) BiCMOS curvature corrected bandgap voltage reference circuit design is presented in this paper. This voltage reference circuit shows promising thermal performances. The simulated design has a temperature coefficient of only 0.661 ppm/°C in the temperature range between -40°C and 125°C with 5 V power supply and <;1 ma current without a buffer. The proposed bandgap voltage reference circuit is designed using 180 nm process models for the CMOS devices and generic models for the BJT devices.
