Abstract :
The measured temperature and supply voltage dependences of a bandgap reference (BGR) circuit first published by Gilbert (1996) and implemented in IBM´s SiGe BiCMOS process agree well with model predictions. The plot of VBGR against temperature exhibits less curvature than predicted elsewhere for SiGe BGRs
