Yangbo Yi · Dianzi qijian · 2007
A novel CMOS reference,which is based on the temperature coefficient of threshold voltage and mobility,is presented in this paper.The circuit can provide a voltage reference and a current reference with low temperature coefficient simultaneously.The proposed reference has been fabricated in 3 μm CMOS process.The experiment result manifests that the reference voltage is approximately 763 mV and the temperature coefficient is 92×10-6/℃.The voltage changes less than 6.6 mV from 0 to 100℃.The reference has been used in DC-DC converters successfully.
