A Current Compensated Bandgap Reference Circuits
Guangyuan Shi · Journal of Liaoning University · 2008
A traditional Bandgap Reference Circuits could produce a reference voltage whose temperature coefficient is about 15 ppm/℃.In a circuit,the positive temperature coefficient has a close relationship with the branch circuit currents.The circuit presented in this paper produces a reference voltage of which the temperature coefficient is about 3 ppm/℃ by adjusting the values of the branch circuit current when the temperature ranges from-30 ℃ to 110℃.
