A bandgap reference circuit is presented in a 0.13 μm process. Switching techniques are used to eliminate the effects of mismatch in the op amp and current source devices. A novel leakage current compensation technique allows bandgap operation to 200°C. The circuit demonstrates a variation of 1.6 mV over 150°C and has a temperature coefficient of 13.3 ppm/°C. A digital control block necessary for the switching technique is also presented.
