Abstract
This paper discusses the impact of the substrate noise generated by power switches through common substrate in bandgap voltage reference circuits, which have NPNs as main elements. It also analyzes how substrate noise affects NPN device´s performance and then makes output reference voltage dc shifted in some types of bandgap circuit, which is a very fatal error in system. This analysis method of bandgap dc shift is suitable for other bandgap circuits in noisy substrate
