A high precision programmable bandgap voltage reference design for high resolution ADC

Zhu Tiancheng, Yao Suying, and Li Binqiao(School of Electronic Information Engineering, Tianjin University, Tianjin 300072, China)  
A programmable high precision bandgap reference is presented, which can meet the accuracy requirements for all technology corners while a traditional bandgap reference cannot.This design uses SMIC 0.18 μm 1P4M CMOS technology.The theoretically achievable temperature coefficient is close to 0.69 ppm/°C over the whole temperature range.
